No. 63/027,427, filed May 20, 2020, and entitled “Ingestible Device for Delivery of Therapeutic Agent to the Gastrointestinal Tract”; and U.S. Ser. No. 63/086,630, filed Oct. 2, 2020, and entitled “Ingestible Device for Delivery of Therapeutic Agent to the Gastrointestinal Tract.” The entire disclosure of each of these applications is incorporated by reference herein.

FIELD

The disclosure generally relates to ingestible devices capable of delivering a dispensable substance, such as a therapeutic agent, as well as related components, systems and methods.

BACKGROUND

The gastrointestinal (GI) tract generally provides a therapeutic medium for an individual's body. At times, it is desirable to dispense therapeutic agents to the GI tract to treat a medical condition.

SUMMARY

The disclosure provides ingestible devices that can directly deliver therapeutic agents to desired tissue(s) of the GI tract of a subject, such as the submucosa, the mucosa, and/or the mucus layer of the GI tract, and methods of using the same. The ingestible devices can deliver therapeutic agents in a safe, effective, and reliable manner. The disclosure also provides pharmaceutical compositions for use in methods of treating a disease or condition in a subject in need thereof.

Ingestible devices of the present disclosure are configured to provide at least three different modes of direct delivery of therapeutic agents to the GI tract of a subject, referred to herein as trans-epithelial, epithelial, and topical delivery. Direct delivery, as used herein, refers to a force-driven delivery mechanism.

Thus, in one aspect, this disclosure relates to trans-epithelial delivery of a therapeutic agent to the GI tract of a subject. Accordingly, the disclosure provides an ingestible device that can directly deliver a therapeutic agent past the epithelial cell layer of the mucosa of the GI tract of a subject to yield systemic exposure of the therapeutic agent to the subject. In such embodiments, the ingestible device is configured to directly deliver the therapeutic agent past the epithelial cell layer of the mucosa and into the submucosa and/or into a region of the mucosa beneath the epithelial layer (e.g., into the lamina propria) of the GI tract, where it is available for systemic uptake. This can be particularly relevant when the oral bioavailability of the therapeutic agent is otherwise low. In some embodiments, systemic exposure of the therapeutic agent is achieved by trans-epithelial delivery of the therapeutic agent into the submucosa and/or into a region of the mucosa beneath the epithelial layer (e.g., into the lamina propria) of the small intestine, for example, in the duodenum, the jejunum, and/or the ileum. In further embodiments, the trans-epithelial delivery directly delivers the therapeutic agent into the submucosa submucosa and/or into a region of the mucosa beneath the epithelial layer (e.g., into the lamina propria) of the GI tract such that the percent systemic uptake of the trans-epithelial delivery relative to intravenous or subcutaneous administration is at least about 10% (e.g., at least about 15%, at least about 20%, at least about 25% or more).

Without wishing to be bound by theory, it is believed that trans-epithelial delivery to the submucosa and/or into a region of the mucosa beneath the epithelial layer (e.g., into the lamina propria) of the GI tract is achieved by using an appropriate value for one or more performance parameters associated with the ingestible device configured for such use. Such performance parameters include, for example, internal pressure of the ingestible device, peak fluid pressure of the ingestible device, nozzle pressure of the ingestible device, peak jet power of the dispensable substance (e.g., a pharmaceutical formulation containing the therapeutic agent) delivered from the ingestible device, peak jet velocity of the dispensable substance (e.g., a pharmaceutical formulation containing the therapeutic agent) delivered from the ingestible device, peak jet pressure of the dispensable substance (e.g., a pharmaceutical formulation containing the therapeutic agent) delivered from the ingestible device, peak jet force of the dispensable substance (e.g., a pharmaceutical formulation containing the therapeutic agent) delivered from the ingestible device, peak jet stable length of the dispensable substance (e.g., a pharmaceutical formulation containing the therapeutic agent) delivered from the ingestible device, nozzle shape, nozzle length and nozzle diameter.

In another aspect, this disclosure relates to epithelial delivery of a therapeutic agent to the GI tract of a subject. Accordingly, the disclosure provides an ingestible device configured to directly deliver the therapeutic agent into the mucus and/or onto the epithelial layer, but not past the epithelial layer of the mucosa, of the small or large intestine, from which it can act locally, and in some cases away from the site of direct delivery. In some embodiments, the device is configured so that the therapeutic agent is delivered from the device with sufficient force to provide the epithelial delivery, the force being lower than that required for trans-epithelial delivery.

In yet another aspect, this disclosure relates to topical delivery of a therapeutic agent to the GI tract of a subject. Accordingly, the disclosure provides an ingestible device configured to deliver the therapeutic agent into the lumen and/or onto the mucus or other surface of the GI tract facing the lumen of the small or large intestine, from which it can act locally, and in some cases away from the site of delivery. In some embodiments, the device is configured so that the therapeutic agent is delivered from the device with sufficient force so that the therapeutic agent is delivered topically, the force being lower than that required for the epithelial or the trans-epithelial delivery.

The ingestible device, whether configured for trans-epithelial, epithelial or topical delivery, can have a streamlined and/or relatively simple mechanical design, be relatively small, and/or be inexpensive to manufacture. In general, the device protects a dispensable substance (e.g., a therapeutic agent, or a pharmaceutical formulation comprising the therapeutic agent) until the device reaches a desired location of the subject. As an example, the device can be designed to deliver dispensable substance to a desired location in the GI tract of a subject, and the device can be designed so that the dispensable substance is not subject to constituents of the GI tract (e.g., acids, enzymes) prior to reaching the desired location in the GI tract. As another example, the device can be designed to deliver dispensable substance such that the therapeutic properties of the dispensable substance are not altered during delivery (e.g., the dispensable substance is a therapeutic agent that binds its therapeutic target after delivery).

The present disclosure provides ingestible devices that can directly deliver therapeutic agents to desired tissue(s) of the GI tract of a subject (such as the submucosa, the mucosa, and/or the mucus layer of the GI tract), e.g., to treat a particular class of disease, or a specific disease. Relatedly, methods of using the device to deliver the therapeutic agents to desired tissue(s) of the GI tract, e.g., to treat a particular class of disease, or a specific disease, are disclosed. These disclosures also inherently provide disclosures of corresponding medical uses—that is, disclosures of the recited therapeutic agents for use in a method of treating the recited class of disease, or specific disease, by using the device to deliver the recited agents to desired tissue(s) of the GI tract of a subject.

Definitions

“Ingestible,” as used herein in reference to the device, means that the device can be swallowed whole.

“Dispensable” as used herein with reference to any substance, refers to any substance that may be released from an ingestible device as disclosed herein, or from a component of the device such as a reservoir. For example, a dispensable substance may be a therapeutic agent as disclosed herein, and/or a formulation that includes a therapeutic agent as disclosed herein. A dispensable substance may be a fluid, such as a liquid, a suspension or a semi-solid. For example, a dispensable substance can be a liquid in the form of a solution, such as an aqueous solution. In some embodiments, when disposed in an ingestible device, a substance is a non-fluid, such as a solid. In such embodiments, the substance may be converted to a fluid prior to being delivered from the ingestible device. In some embodiments, the therapeutic agent is a small molecule. In other embodiments, the therapeutic agent is a large molecule, such as a biologic drug. Nonlimiting examples of biologic drugs include antibodies (including monoclonal antibodies), proteins (including fusion proteins), peptides (including cyclic peptides), cells (including stem cells), and nucleic acids (including inhibitory nucleic acids, antisense nucleic acids, siRNA, ribozymes). In some embodiments, the dispensable substance is a pharmaceutical formulation comprising a therapeutic agent and a liquid carrier. In some embodiments, the pharmaceutical formulation comprising the therapeutic agent and the liquid carrier is a solution formulation. In other embodiments, the pharmaceutical formulation comprising the therapeutic agent and the liquid carrier is a suspension formulation, or an emulsion formulation. In some embodiments, a dispensable substance delivered as described herein is particularly well-suited for treatment of diseases and conditions of the endoderm, for example, it may be more efficacious in gut-associated lymphoid tissue (GALT) or the hepatic system as compared to subcutaneous or intravenous administration. In general, the viscosity of a dispensable substance can be selected as appropriate. In some embodiments, the dispensable substance has a viscosity of at least about 0.5 centiPoise (cP) (e.g., at least about 0.8 cP, at least about 1 cP, at least about 2 cP, at least about 3 cP, at least about 4 cP, at least about 5 cP, at least about 10 cP, at least about 15 cP, at least about 25 cP, at least about 50 cP) and/or at most about 100 cP (e.g., at most about 75 cP, at most about 65 cP, at most about 50 cP, at most about 25 cP, at most about 20 cP, at most about 10 cP at most about 9 cP, at most about 8 cP, at most about 7 cP). In certain embodiments the dispensable substance has a viscosity of from about 0.5 cP to about 10 cP (e.g., from about 0.8 cP to about 9 cP, from about 0.8 cP to about 8 cP). In some embodiments, the dispensable substance has a viscosity of from about 0.5 cP to about 100 cP (e.g., from about 1 cP to about 100 cP, from about 1 cP to about 50 cP, from about 1 cP to about 25 cP, from about 1 cP to about 20 cP, from about 1 cP to about 15 cP, from about 1 cP to about 10 cP, from about 5 cP to about 100 cP, from about 10 cP to about 100 cP, from about 25 cP to about 100 cP, from about 25 cP to about 75 cP, from about 25 cP to about 50 cP).

As used herein, the term “enteric” refers a material that permits transition to a desired location in the GI tract (e.g., through the stomach to the intestine) before being dissolved/degraded/eroded due to exposure of certain conditions (e.g., pH, temperature, enzymes) of the GI tract. An enteric material may prevent a drug from degradation by gastric fluid and enzymes. In some embodiments, an enteric composition (e.g., when formed as a coating on the housing of an ingestible device) is selected from mixtures of fats and fatty acids; shellac and shellac derivatives; and cellulose acetate phthalates. An enteric material can be an enteric polymer. In some embodiments, an enteric polymer can remain insoluble in the stomach, but dissolve at the higher pH of the intestine (e.g., small intestine or large intestine), and are used to deliver drugs to the intestine. Examples include Colorcon's Opadry Enteric 91 series Polyvinyl Acetate Phthalate, Opadry Enteric 94 series Methacrylic Acid, Opadry Enteric 95 series Methacrylic Acid, Sureteric PVAP (Polyvinyl Acetate Phthalate), Nutrateric Ethylcellulose Evonik Acryl-EZE (Colorcon & Evonik collaboration—Eudragit L 100-55 Mixture Methacrylic copolymers); Evonik's Eudragit L 100-55 Methacrylic copolymers, Eudragit L 30 D-55 Methacrylic copolymers (30%), EudragitL 100 Methacrylic copolymers, EudragitL 12,5 Methacrylic copolymers (12.5%), Eudragit S 100 Methacrylic copolymers, Eudragit S 12,5 Methacrylic copolymers (12.5%), Eudragit FS 30 D Methacrylic copolymers (30%); Kerry's SheffCoat ENT Cellulose Acetate Phthalate, Acrylate copolymer, HPMC-P; Eastman's C-A-P NF Cellulose Acetate Phthalate; Sensient's PROTECT™ ENTERIC Shellac & Sodium Alginate. In certain embodiments, an enteric material dissolves in the small intestine and is suitable for small intestine release. Examples of such enteric materials include, but are not limited to, cellulose derivatives, e.g., cellulose acetate phthalate, hydroxypropylmethylcellulose phthalate (HPMCP), hydroxypropylmethylcellulose acetate succinate (HPMCAS) and RL100 (e.g., HP-55), malic acid-propane 1,2-diol, polyvinyl acetate phthalate, anionic polymers of methacrylic acid and methyl methacrylate, hydroxypropylcellulose acetate phthalate, polyvinyl acetate phthalate, methacrylate-methacrylic acid copolymers, styrol, maleic acid copolymers, shellac, and others. Another suitable enteric material is a water emulsion of ethylacrylate methylacrylic acid copolymer, or hydroxypropyl methyl cellulose acetate succinate (HPMAS). (See, e.g., U.S. Pat. No. 5,591,433). In some embodiments, an enteric material dissolves in the large intestine and is suitable for colonic release. Enteric materials suitable for large intestine (e.g., colonic) release are known to one of skill in the art. In some embodiments, degradation of the coating is microbially triggered, e.g., the bacteria in the colon enzymatically trigger degradation of the coating (see, e.g., Archana et al., Int. J. Pharm. Sci. Res. 1(5):40-47 (2016); and Sethi et al., Int. J. Pharm. Sci. Res. 3(9):2989-3000 (2012)). In some embodiments, the coating is a pH-dependent polymer that is insoluble at low pH but becomes increasingly soluble as pH increases. In some embodiments, the coating is a polymethacrylates with a pH-dependent dissolution threshold of about pH 6.0 to about 7.0. Examples of suitable enteric materials include, but are not limited to, chitosan, alginates (e.g., as calcium salts), Eudragit® L (e.g., Eudragit® 100), Eudragit® S (e.g., Eudragit® S 100), Eudragit® L (e.g., Eudragit® L-30D), Eudragit® FS (e.g., Eudragit® FS 30D), hydroxypropylmethylcellulose phthalate 50, hydroxypropylmethylcellulose phthalate 55, and cellulose acetate trimellate. In some embodiments, an enteric material is a material described in U.S. Pat. No. 10,226,430; Sethi et al., Int. J. Pharm. Sci. Res. 3(9):2989-3000 (2012); or Archana et al., Int. J. Pharm. Sci. Res. 1(5):40-47 (2016), each of which are herein incorporated by reference in their entireties. In some embodiments, the colon-specific degradation of an enteric material can be based on the presence of microorganisms that reside only in the colon, more particularly, biodegradable enzymes produced by these microorganisms. In general, such microorganisms are anaerobic bacteria, e.g., Bacteroides, Bifidobacteria, Enterobacteria, Eubacteria, Clostridia, Enterococci, and Ruminococcus, etc. These micro floras fulfill their energy needs by fermenting various types of substrates that have been left undigested in the small intestine, e.g., polysaccharides, di- and tri-saccharides, etc. These polymers are stable in the environments of the stomach and small intestine. On reaching the colon, the polymers undergo degradation by the enzyme or break down of the polymer backbone leads to a subsequent reduction in their molecular weight and thereby loss of the mechanical strength.

The term “jet,” as used herein, refers to a collimated stream of fluid, e.g., liquid or suspension, that is stable without breaking up into a spray. A jet may be formed by forcing the fluid, e.g., liquid or suspension, through an opening in an ingestible device.

As used herein, “peak fluid pressure” refers to maximum pressure generated in the fluid volume. Generally, the peak fluid pressure is achieved at initial delivery of the dispensable substance from the ingestible device. In some embodiments, peak fluid pressure is referred to herein as “internal pressure on the pharmaceutical formulation in the device, prior to release from the device.”

As used herein, “minimum fluid pressure” refers to minimum pressure generated in the fluid volume. Generally, the minimum fluid pressure is achieved at the end of delivery of the dispensable substance from the ingestible device.

“Fluid pressure during delivery,” as used herein, refers to the pressure in the fluid volume as it decreases during the delivery process.

As used herein, “nozzle” refers to a channel between a fluid reservoir space and an external environment. Generally, in embodiments in which a nozzle is used, pressure in the fluid volume generates a high speed flow of fluid through the nozzle to produce a fluid jet at the opening of the nozzle through which the dispensable substance leaves the ingestible device and enters an environment exterior to the ingestible device.

“Nozzle diameter,” as used herein, refers to the diameter of the opening of the nozzle at the opening of the nozzle through which the dispensable substance leaves the ingestible device and enters an environment exterior to the ingestible device.

As used herein, “nozzle length” refers to the length of the opening of the nozzle.

“Nozzle stand-off distance,” as used herein, refers to the distance between: 1) the opening of the nozzle through which the dispensable substance leaves the ingestible device and enters an environment exterior to the ingestible device; and 2) the interface of the lumen and the surface of the GI tract facing the lumen.

As used herein, the “internal pressure” of an ingestible device refers to the pressure applied to a dispensable substance, such as a therapeutic agent, or a formulation containing a therapeutic agent, contained in the ingestible device prior to delivery of the dispensable substance from the ingestible device. In some embodiments, the internal pressure is provided by the drive force generator of the ingestible device. In certain embodiments, the internal pressure is greater than the fluid pressure. This may be due, for example, to friction, such as O-ring friction, acting on the drive coupling of the ingestible device. This friction is referred to herein as the “piston friction.”

“Nozzle pressure” as used herein refers to the pressure of a dispensable substance at a nozzle opening as measured at the surface facing the interior of the nozzle as the dispensable substance is delivered from the ingestible device. In general, for a given ingestible device at a given point in time, the nozzle pressure is approximately the same as the fluid pressure.

“Topical delivery” or “topical administration,” as used herein, refers to a route of administration of a dispensable substance (for example, a therapeutic agent or a pharmaceutical formulation containing a therapeutic agent) where the dispensable substance is delivered to a localized area of the body or to the surface of a body part, regardless of the location of the effect; more particularly, the topical administration of the dispensable substance comprises releasing the dispensable substance to the lumen of the GI tract, a surface of the GI tract facing the lumen, a mucous membrane and/or a lining of the gastrointestinal tract of a subject, including, but not limited to, a surface, mucous membrane or lining containing one or more disease sites, such as gastrointestinal mucosal lesions. The effect of the topical delivery or topical administration of the dispensable substance may be local to, or away from (e.g., distal to), the site of the topical administration.

“Epithelial delivery” or “epithelial administration,” as used herein, refers to a route of administration of a dispensable substance (for example, a therapeutic agent or a pharmaceutical formulation containing a therapeutic agent) where the dispensable substance is directly delivered into the mucus or onto the epithelium, but not past the epithelial layer, of the GI tract of a subject, such as the small or large intestine, from which the dispensable substance can act locally or peripherally. In some embodiments of epithelial delivery or epithelial administration, the therapeutic agent can move deeper into the GI tissue (i.e., past the epithelial layer) away from the site of direct delivery, such as, for example, via diffusion or active transport.

“Trans-epithelial delivery” or “trans-epithelial administration,” as used herein, refers to a route of administration of a dispensable substance (for example, a therapeutic agent or a pharmaceutical formulation containing a therapeutic agent) where the dispensable substance is directly delivered through the epithelial layer of the mucosa of the GI tract to the submucosa of the GI tract of a subject; optionally, at least a portion of the dispensable substance is directly delivered past the epithelial layer to a region of the mucosa beneath the epithelial layer. In embodiments of trans-epithelial delivery in which a portion of the dispensable substance is directly delivered to a region of the mucosa beneath the epithelial layer, at least some (e.g., all) of the portion of the dispensable substance is directly delivered to the lamina propria. Once the therapeutic agent or a pharmaceutical formulation containing a therapeutic agent is directly delivered past the epithelial layer of the GI tract, it is available for systemic exposure of the therapeutic agent to the subject.

General Introduction

FIG. 1A schematically describes the different regions of healthy intestinal tissue, presented in a cross section. The regions include the lumen of the GI tract, the mucus of the GI tissue, the mucosa of the GI tissue and the submucosa of the GI tissue. The mucosa of the GI tissue includes the epithelial layer and the lamina propria. The muscularis mucosae separates the mucosa from the submucosa. The muscularis extrema is below the submucosa. FIG. 1B schematically describes corresponding regions of diseased intestinal tissue, presented in a cross section.

An ingestible device described herein can deliver a therapeutic agent via topical delivery (without being directly delivered to the mucus, mucosa or submucosa), epithelial delivery (directly delivered to the mucus or epithelium without being directly delivered past the epithelial layer to the mucosa or submucosa) or trans-epithelial delivery (directly delivered to the submucosa and/or into a region of the mucosa beneath the epithelial layer, such as the lamina propria.

In general, the form of delivery may depend on the design of the ingestible device and parameters used with the device (e.g., internal pressure, fluid pressure, number of nozzles, design of nozzles). Holding other parameters constant, at relatively low fluid pressures and/or internal pressures, the therapeutic agent may be topically delivered, while higher fluid pressures and/or internal pressures may result in epithelial delivery, and still higher fluid pressures and/or internal pressure may result in trans-epithelial delivery. During trans-epithelial delivery, a bolus of the therapeutic agent initially contained in the dispensable substance may form within the submucosa and/or into a region of the mucosa beneath the epithelial layer, such as the lamina propria.

In some embodiments, the following holds. The ingestible device is designed to deliver a dispensable substance, for example, a therapeutic agent or a pharmaceutical formulation containing a therapeutic agent through the epithelial layer of the mucosa of the GI tract. In some embodiments, the dispensable substance is a solution formulation; optionally, a suspension. In some embodiments, the dispensable substance enters the submucosa and/or into a region of the mucosa beneath the epithelial layer, such as the lamina propria, of the small intestine, where it can be absorbed systemically. After the patient swallows the device, it passes through the GI tract and eventually reaches the small intestine. The device includes a restraining mechanism, an optionally a triggering mechanism (e.g., a degradable and/or erodible coating, such as an enteric coating, that partially or completely degrades and/or erodes when the device reaches the desired location in the GI tract). The desired location can be the small intestine or the large intestine. When the device is configured for trans-epithelial GI tract delivery to the submucosa submucosa and/or into a region of the mucosa beneath the epithelial layer, such as the lamina propria, the preferred location can be the small intestine. With the restraining element is removed, relative movement between certain components (e.g., sliding of a component) occurs such that one or more openings in the ingestible device (e.g., in a compartment containing the dispensable substance, such as a reservoir, sometimes referred to herein as the “drug reservoir,” “storage reservoir” or “substance reservoir”) become aligned with one or more additional openings (e.g., one or more nozzles) in the ingestible device (e.g., in the housing). With the ingestible device now in this open position, a force (e.g., generated by a force generator and/or transferred by a drive coupling, such as a membrane or a piston) forces the dispensable substance from the drug reservoir out of the device via the one or more openings (e.g., the one or more nozzles). The dispensable substance is delivered as a jet of fluid (e.g., liquid) through the epithelial layer of the mucosa and directly into the submucosa and/or into a region of the mucosa beneath the epithelial layer, such as the lamina propria, of the GI tract in the form of single or multiple boluses. After swallowing the device, the device travels through the GI tract (mouth, esophagus, stomach, duodenum, jejunum, ileum, cecum and colon), ultimately exiting the GI tract via the anus.

Thus, in general, the ingestible devices disclosed herein provide delivery of therapeutic agent to the GI tract of a subject. In one aspect, the disclosure relates to trans-epithelial delivery of a dispensable substance (e.g., a therapeutic agent or a formulation comprising a therapeutic agent) to the GI tract of a subject. Accordingly, the disclosure provides an ingestible device that can directly deliver a dispensable substance (e.g., a therapeutic agent or a formulation comprising a therapeutic agent) to the submucosa and/or into a region of the mucosa beneath the epithelial layer, such as the lamina propria, of the GI tract of a subject, which may result in systemic exposure of the therapeutic agent to the subject. In such embodiments, the ingestible device is configured to directly deliver the dispensable substance past the epithelial cell layer of the mucosa and into the submucosa and/or into a region of the mucosa beneath the epithelial layer, such as the lamina propria, of the GI tract, where the therapeutic agent so delivered is available for systemic uptake. In some embodiments, systemic exposure of the therapeutic agent is achieved by trans-epithelial delivery of the dispensable substance into the submucosa and/or into a region of the mucosa beneath the epithelial layer, such as the lamina propria, of the small intestine, for example, in the duodenum, the jejunum, and/or the ileum. In some further embodiments, the trans-epithelial delivery directly delivers the dispensable substance into the submucosa and/or into a region of the mucosa beneath the epithelial layer, such as the lamina propria, of the GI tract such that the percent systemic uptake of the therapeutic agent via the trans-epithelial delivery relative to intravenous or subcutaneous administration is at least about 10% (e.g., at least about 15%, at least about 20%, at least about 25% or more).

In some embodiments, the direct delivery of the therapeutic agent to the submucosa and/or into a region of the mucosa beneath the epithelial layer, such as the lamina propria, via trans-epithelial delivery may also or alternatively provide therapeutic effects locally and/or away from (e.g., distal to) the site of the direct delivery.

In some embodiments, the trans-epithelial delivery may directly deliver a first portion of the dispensable substance to the submucosa of the GI tract, and a second portion of the dispensable substance to the mucosa, all or a further portion of which may be directly delivered to the lamina propria. In some embodiments, the second portion of the dispensable substance delivered to the mucosa, such as the lamina propria, of the GI tract via the trans-epithelial delivery may provide therapeutic effects locally and/or away from (e.g., distal to) the site of the direct delivery.

In another aspect, the disclosure relates to epithelial delivery of a dispensable substance (e.g., a therapeutic agent or a formulation comprising a therapeutic agent) to the GI tract of a subject. Accordingly, the disclosure provides an ingestible device configured to directly deliver a dispensable substance (e.g., a therapeutic agent or a formulation comprising a therapeutic agent) into the mucus, but not past the epithelial layer of the mucosa, of the small or large intestine, from which it may provide therapeutic effects locally and/or away from (e.g., distal to) the site of the direct delivery. In some further embodiments, the ingestible device directly delivers the dispensable substance such that it contacts the surface of the epithelial cell layer of the mucosa facing the lumen, but as previously noted, the epithelial delivery does not directly delivery the dispensable substance past the epithelial layer of the mucosa. In some embodiments, the device is configured so that the dispensable substance is delivered from the device with sufficient force to provide the epithelial delivery, the force being lower than that required for trans-epithelial delivery to the GI tract. In some further embodiments, the epithelial delivery directly delivers the dispensable substance into the mucus of the GI tract such that the percent systemic uptake of the therapeutic agent via the epithelial delivery relative to intravenous or subcutaneous administration is greater than that for topical delivery, but less than for trans-epithelial delivery. In other embodiments, the epithelial delivery directly delivers the dispensable substance into the mucus of the GI tract such that the percent systemic uptake of the therapeutic agent via the epithelial delivery relative to intravenous or subcutaneous administration is about 0.5% to about 10% or more (e.g., about 0.5%, about 2%, about 3%, about 4%, about 5%, about 6%, about 7%, about 8%, about 9%, about 10%, or more).

In some embodiments of epithelial delivery, the therapeutic agent directly delivered into the mucus of the GI tract via the epithelial delivery may undergo active or passive transport or diffusion past the epithelial layer. Once past the epithelial layer, the therapeutic agent may provide therapeutic effects locally and/or away from (e.g., distal to) the site of the direct delivery. In some embodiments, the therapeutic agent binds to a therapeutic target present in the GI epithelial layer or elicits other pharmacodynamic effects locally or away from the site of delivery via immune cells or tissue in the GI tract (e.g., dendritic cells, lymphocytes, mucosa-associated lymphoid tissue).

In yet another aspect, this disclosure relates to topical delivery of a dispensable substance (e.g., a therapeutic agent or a formulation comprising a therapeutic agent) to the GI tract of a subject. Accordingly, the disclosure provides an ingestible device configured to deliver the dispensable substance (e.g., a therapeutic agent or a formulation comprising a therapeutic agent) into the lumen and/or onto the mucus or other surface (e.g., a diseased surface) of the GI tract facing the lumen of the small or large intestine, from which it may provide therapeutic effects locally and/or away from (e.g., distal to) the site of delivery. In some embodiments, the device is configured so that the dispensable substance is delivered from the device with sufficient force so that the dispensable substance is delivered topically, the force being lower than that required for the epithelial or the trans-epithelial delivery to the GI tract. In some embodiments, the topical delivery to the GI tract results in reduced systemic uptake of the therapeutic agent compared to trans-epithelial delivery to the GI tract, intravenous or subcutaneous delivery.

In some further embodiments, topical delivery delivers the dispensable substance into the lumen and/or onto the mucus or the other surface facing the lumen of the GI tract such that the percent systemic uptake of the therapeutic agent via the topical delivery relative to intravenous or subcutaneous administration is less than about 20%, less than about 10%, less than about 5%, less than about 4%, less than about 3%, less than about 2% or less than about 1%. In some embodiments, the topical delivery to the GI tract results in negligible or no systemic uptake of the therapeutic agent compared to trans-epithelial delivery to the GI tract, intravenous or subcutaneous delivery.

In some embodiments, the topically delivered dispensable substance may spread over the mucus or other surface facing the lumen of the GI tract, thereby coating the surface of the GI tract at or away from (e.g., distal to) the site of delivery. In some embodiments, upon or after the dispensable substance has been topically delivered, the therapeutic agent may undergo transport (e.g., diffusion) from the surface of the mucus into the mucus, and optionally, active or passive transport or diffusion past the epithelial layer of the mucosa.

In some embodiments, the mucus and/or epithelial layer of the mucosa may be disrupted or even absent, such as in a patient having a disease or condition of the GI tract. In such embodiments, the topical delivery of the dispensable substance to the GI tract of the patient may provide direct delivery of the dispensable substance to the surface of the GI tract facing the lumen, such as mucosal tissue exposed by said disruption and/or absence (e.g., both the mucus layer and/or epithelial layer are completely or partially absent or compromised in portions of the GI tract due to a disease or condition). For example, in some embodiments, the topical delivery of the dispensable substance to the GI tract of the patient may provide topical delivery to one or more lesions of the GI tract. In some embodiments, the disease or condition is an inflammatory bowel disease. In some further embodiments, the inflammatory bowel disease is ulcerative colitis. In some other embodiments, the inflammatory bowel disease is Crohn's disease.

Accordingly, provided herein are new systemic delivery devices and methods that deliver therapeutic agents into the small intestinal mucosa and/or submucosa by jet injection. Current methods of administration for most large molecule therapeutic agents are subcutaneous (SC), intramuscular (IM), or bolus intravenous (IV) injection targeting the systemic circulation. The devices and methods described herein provide an alternative route of administration to current injectable medications, which can lead to greater convenience and compliance since they minimize or avoid the logistical challenges, patient compliance and adherence challenges, pain, and discomfort associated with traditional routes of administration.

Also, by providing a higher concentration of therapeutic in GI tissue, the devices and methods described herein are particularly well-suited for treatment of diseases and conditions of the endoderm, including the liver.

Device Description

General

In general, the ingestible device is suitable for swallowing by a patient and for safely and effectively passing through the GI tract of the patient. Generally, the device can be in the shape of a capsule, a pill or any other swallowable form that may be orally consumed by the subject. In some embodiments, the ingestible device can be swallowed voluntarily under medical supervision or in a home use environment with instruction provided ahead of subsequent ingestion. Generally, ingestible devices are intended for single subject, single use. The ingestible device can have a density high enough to cause the ingestible device to sink within human stomach fluid, e.g., the unfilled ingestible device can have a density of greater than 1.01 g/cm³. The ingestible device can have maximum dimensions that allow the ingestible device to pass through an average human GI tract. In some embodiments, the ingestible device is configured to prevent tumbling in the small intestine of a human. For example, the ingestible device is of sufficient length whereby it will not tumble in the small intestine of a human before, during, or after the dispensable substance is released. Generally, the ingestible device is configured to deliver a sufficient amount of therapeutic agent contained in the dispensable substance to be effective for its intended purpose. In general, the ingestible device's patient-contacting portions (e.g., exterior surface) and dispensable substance-contacting portions are biocompatible. Preferably, the device can withstand an indirect bite force without damaging the housing damage or resulting in leakage. As an example, when containing the dispensable substance, the ingestible device can withstand a bite force of at least about 60 Newtons (N). Generally, unless otherwise intended (see discussion below) components of the ingestible device can withstand exposure to a pH range expected in the human GI tract without substantial loss of functionality, substantial structural damage, or substantial leakage. As an example, in some embodiments, the ingestible device can withstand submersion in a pH 1.5±0.5 fluid environment for at least about 24 hours without substantial loss of functionality, substantial structural damage, or substantial leakage. In general, the ingestible device can maintain an external fluid barrier between the inside of the ingestible device and the GI tract of the subject during transit therethrough. Generally, the ingestible device can withstand external fluid pressures to which it is exposed during use without substantial loss of functionality, substantial structural damage, or substantial leakage. As an example, in some embodiments, the ingestible device undergoes no substantial loss of functionality, substantial structural damage, or substantial leakage when exposed to a sustained pressure of at least about 2 psig for at least about 24 hours and/or when exposed to a momentary pressure of at least about 5 psig momentary pressure for at least about 1 minute.

In general, an ingestible device disclosed herein includes the following features.

Housing

In some embodiments, the ingestible device comprises a housing configured to maintain its mechanical integrity during use of the ingestible device. In some embodiments, the housing has a first portion and a second portion. In some further embodiments, the housing has a first actuation component on the housing, and a second actuation component within the housing. In some embodiments, a storage reservoir is located within the housing, wherein the storage reservoir is configured to store a dispensable substance. In some embodiments, the housing has an opening in fluid communication with the storage reservoir. In some embodiments, the ingestible device employs an electrolytic mechanism for creating one or more openings in the ingestible device, wherein a substance can be dispensed through said opening as described in PCT Application Number PCT/US2019/021814, which published as WO2019178071, and which is incorporated by reference herein. For example, the housing may comprise an external electrolytic circuit (electrolytically erodible surface being on the exterior of the device), whereby the surrounding gastric fluids are the electrolyte that completes an electrolytic circuit between anode and cathode. With sufficient bias voltage (e.g., 1.5-15 volts, such as 3-5 volts), the anode will dissolve or erode electrolytically and thus create an opening in the housing within a desired time interval. In some embodiments, the one or more openings created by an electrolytic mechanism are coupled to one or more nozzles, thereby allowing for trans-epithelial, epithelial, or topical delivery as described herein. In some embodiments an ingestible device includes an enteric coating on the housing. In certain embodiments, the enteric coating covers only certain regions of the housing. The housing may be designed to withstand the chemical and mechanical environment of the GI tract (e.g., effects of muscle contractile forces and concentrated hydrochloric acid in the stomach). A broad range of materials that may be used for the housing. Examples of these materials include, but are not limited to, thermoplastics, fluoropolymers, elastomers, stainless steel, and glass complying with ISO 10993 and USP Class VI specifications for biocompatibility; and any other suitable materials and combinations thereof. In certain embodiments, these materials may further include liquid silicone rubber material with a hardness level of 10 to 90 as determined using a durometer (e.g., MED-4942™ manufactured by NuSil™), a soft biocompatible polymer material such as, but not limited to, polyvinyl chloride (PVC), polyethersulfone (PES), polyethylene (PE), polyurethane (PU) or polytetrafluoroethylene (PTFE), and a rigid polymer material coated with a biocompatible material that is soft or pliable (e.g., a poly(methyl methacrylate) (PMMA) material coated with silicone polymer). Use of different materials for different components may enable functionalization of certain surfaces for interaction with proteins, antibodies, and other biomarkers. For example, Teflon® may be used as a material in the ingestible device for movable components in order to reduce friction between these components. Other example materials may include other materials commonly used in micro-fabrication, such as polydimethylsiloxane (PDMS), borosilicate glass, and/or silicon. Although specific materials may be referred to herein as being used to construct the device for illustrative purposes, the materials recited are not intended to be limiting, and one skilled in the art may easily adapt the device to use any number of different materials without affecting the overall operation or functionality of the device. In some embodiments, the housing of the ingestible device may be manufactured from a type of plastic, such as a photosensitive acrylic polymer material or an inert polycarbonate material. The housing may also be formed using material that can be sterilized by chemicals. In some embodiments, the wall of the housing may have a thickness of, for example, from about 0.5 millimeter to about 1 millimeter. In some embodiments, in addition to being biocompatible, the material from which the housing is made is non-ferric and non-magnetic. Such materials include various plastics (e.g., PVC, or polycarbonate). Optionally, the housing can include a metal-based material, such as an alloy, stainless steel or a substantially pure metal. Such materials can be sterilized without affecting the mechanical workings of the ingestible device or the exterior surface of the ingestible device. In some embodiments, the metal-based material is compatible with the dispensable substance over long duration of storage. A wide variety of stainless steel alloys satisfy these criteria, including SAE grades 303, 304, 304L, 316, 316L, 440. In consideration of nickel content, purity, and/or traceability, in some embodiments, the stainless steel grade is approved for use as a surgical implant material, such as ASTM grades F138, F1314, F1586, F2229, or F2581. The walls of the housing of the ingestible device generally are sufficiently thick to withstand internal and external pressures to which they are exposed without substantial loss of functionality, substantial structural damage, or substantial leakage. In general, the walls of the housing are desirably as thin as possible to enhance the volume available for containing dispensable substance. As an example, in some embodiments, the walls are from about 0.05 mm to about 0.5 mm thick (e.g., if made of metal-based material, such as stainless steel) or from about 0.1 to about 1 mm thick (e.g., if made of plastic, such as polycarbonate). In general, the housing is made of material with a thermal expansion coefficient low enough that the device does not substantially deform at temperatures encountered during shipping and storage, or within the GI tract. In some embodiments, the walls of the housing are made of an electrolytically erodible surface as described in PCT/US2019/021814, which published as WO2019178071. For example, in some embodiments, the housing includes an electrolytically erodible valve coupled to a nozzle for exposing the liquid volume to its surrounding environment. The exposed metal anode material acting as valve can include a metal alloy or substantially pure metal that is acceptable for human ingestion from consideration of its biocompatibility in the amounts electrolyzed during opening of the valve. It can be desirable to have the thickness of metal in the valve area be small (e.g., to reduce the time and amount of current used to open the valve). For example, the metal portion of the drug container can be 0.025 mm thick across a diameter that matches or slightly exceeds the diameter of the coupled nozzle (e.g., 0.60 mm). In general, the thickness of the metal in the valve area can be in the range 0.002 mm to 0.200 mm.

In some embodiments, the housing of an ingestible device is assembled from multiple modules. For example, in some embodiments, the housing is assembled from two modules. In such embodiments, one of the modules can contain the dispensable substance (“drug module”), and the other module can contain the drive force generator and the drive coupling (“drive module”). Typically, the drug module includes a housing part of appropriate size, shape and material(s) as discussed herein. Usually, the housing part is sterilized, and dispensable substance is subsequently disposed within the housing under aseptic conditions. Optionally a sterile seal (e.g., a sterile foil seal) is incorporated into the drug module. The components of the drug module (e.g., a housing part, a drive force generator, a drive coupling) are assembled in a clean environment. The drug module and the drive module are subsequently combined to form the ingestible device. Representative examples of modules, their separate assembly, and their combination to form an ingestible device, are provide elsewhere herein.

Generally, an ingestible device is sized and shaped for relatively safe and effective movement and intended use within the GI tract of the subject. In certain embodiments, an ingestible device is a capsule having an industry standard size. For example, in some embodiments, an ingestible device is configured as a 00 capsule or a 000 capsule.

In some embodiments, the housing of an ingestible device has an aspect ratio of from about 0.75 to 4 (e.g., from about 1 to about 3, from about 1 to about 2). For example, in some embodiments, the housing aspect ratio is about 1.5:1 (length:diameter). In some other embodiments, the housing aspect ratio is about 2:1 (length:diameter).

In certain embodiments, the housing of an ingestible device has a wall thickness of at least about 0.05 mm (e.g., at least about 0.5 mm, at least about 0.6 mm, at least about 0.7 mm) and/or at most about 1 mm (e.g., at most about 0.9 mm, at most about 0.8 mm).

In certain embodiments, an ingestible device has a wall thickness of from about 0.05 mm to about 0.5 mm. In some embodiments, an ingestible device has a wall thickness of from about 0.1 mm to about 1 mm. In certain embodiments, one region of the housing of an ingestible device may have a wall thickness that is different from that of a different region of the housing of the ingestible device.

In some embodiments, the housing of an ingestible device has an end round that is spline-shaped or that is spherical. In certain embodiments, an ingestible device has an end round that is from about 1 mm to about 2 mm (e.g., about 1.5 mm). In some embodiments, an ingestible device has an end round that is from about 4 mm to about 4.5 mm (e.g., about 4.25 mm). In certain embodiments, an ingestible device has an end round that is from about 4.9 to about 5 mm (e.g., about 4.95 mm). In some embodiments, an ingestible device has an end round that is from about 5.4 mm to about 5.6 mm (e.g., about 5.5 mm).

In certain embodiments, the housing of an ingestible device has an internal volume of at least about 700 μL (e.g., at least about 750 μL, at least about 800 μL, at least about 850 μL) and/or most about 1700 μL (e.g., at most about 1650 μL, at most about 1600 μL, at most about 1500 μL, at most about 1400 μL, at most about 1300 μL, at most about 1200 μL).

In an exemplary embodiment, the housing of an ingestible device has a diameter of about 11 mm, a length of about 26 mm, a wall thickness of about 0.8 mm, an end round of about 1.5 mm, and an internal volume of about 1685 μL.

Fluid Volume

The ingestible device includes a fluid volume to contain a dispensable substance (e.g., a liquid, a suspension). In some embodiments, the fluid volume is completely disposed within the housing. Optionally, the fluid volume can be defined by a storage reservoir. Such a storage reservoir can be a component that can be prepared separately from the housing. In such a storage reservoir, the dispensable substance can be disposed in the storage reservoir before the storage reservoir is associated with the ingestible device.

Dispensable Substance

The device may include one or more dispensable substances, with each dispensable substance including one or more therapeutic agents and/or one or more pharmaceutical formulations including one or more therapeutic agents.

Nozzles

In some embodiments, an ingestible device includes one or more nozzles in fluid communication with the one or more openings in the ingestible device. The nozzle(s) is(are) configured so that the dispensable substance through the nozzle(s) when the dispensable substance is delivered from the ingestible device. In general, a nozzle can have any desired size and shape appropriate for the desired type of delivery of a dispensable substance from the ingestible device. In certain embodiments, a nozzle has a shape and/or size appropriate for trans-epithelial delivery, epithelial delivery or topical delivery. In some embodiments, an ingestible device includes more than one nozzle. For example, an ingestible device can include, for example, up to 50 nozzles (e.g., up to 40 nozzles, up to nozzles, up to 30 nozzles, up to 25 nozzles, up to 20 nozzles, up to 15 nozzles, 10 nozzles). In some embodiments, an ingestible device includes from 2 nozzles to 50 nozzles. In certain embodiments, an ingestible device includes 2 nozzles, three nozzles, four nozzles, five nozzles, six nozzles, seven nozzles, eight nozzles, 10 nozzles, 20 nozzles, 30 nozzles, 36 nozzles, 40 nozzles, 50 nozzles). In some embodiments, the nozzles are arranged at even intervals (optionally pair-wise if an even number of nozzles are used) around the circumference of the device.

Restraining Mechanism

In some embodiments, the ingestible device comprises a restraining mechanism. Generally, a restraining mechanism has a first state in which it is configured to prevent the dispensable substance from exiting the ingestible device via the opening(s), and a second state in which it is configured so that it does not prevent the dispensable substance from exiting the ingestible device via the opening(s). The restraining mechanism can be configured to transition from its first state to its second state when it is exposed to a triggering condition. The restraining mechanism may be provided by one or more restraining elements. The restraining elements can have a first state in which they are configured to prevent the dispensable substance from exiting the ingestible device via the openings, and a second state in which they are configured to allow the dispensable substance to exit the ingestible device via the openings. The restraining elements can be configured to transition from the first state to the second state when the restraining elements are exposed to a triggering condition. In some embodiments, the restraining elements comprise a first type of restraining element and a second type of restraining element different from the first type of restraining element. The first type of restraining element can be configured to transition to its second state before the second type of restraining element transitions to its second state. In some embodiments, a restraining elements comprises a lid, a pin, a band, a plug, a dowel, a clasp, a clamp, a flange, a rivet, an annulus, a torus, a ring, a wafer, a cylinder, an asymmetric shape such as a partial annulus, a partial torus, a partial ring, a partial wafer, a partial cylinder, or any combination thereof (e.g., two partial tori). Optionally, a restraining element can have a filled interior (e.g., no hole). Optionally, a restraining element can have a varying thickness (e.g., a center region that is thinner than the edges). In some embodiments, the restraining elements comprise a plasticizer such as triethyl citrate (TEC). In some embodiments, the restraining elements comprise a degradable and/or erodible material, such as, for example, an enteric material. The enteric material may be degradable and/or erodible in the small intestine of the GI tract, or may be degradable and/or erodible in the large intestine of the GI tract, for example, the colon. In some embodiments, a restraining mechanism can be a mechanism that prevents the dispensable substance from being delivered from the ingestible device even when the drive force generator (or optionally the drive coupling) applies an internal force. For example, such a restraining can be an element (e.g., a pin, a band, a plug) in the opening (e.g., nozzle opening) through which the dispensable substance can be delivered from the ingestible device. Such a restraining element can be formed, for example, of a material that degrades and/or erodes as discussed above.

In general, a restraining mechanism includes a material that will lose a sufficient degree of its mechanical strength at the desired location to cause the ingestible device to deliver the dispensable substance. The material may undergo loss of mechanical strength to any appropriate mechanism or combination of mechanisms, including, for example, moisture ingress, solubility, swelling, leaching, eroding and/or the like.

In some embodiments, a restraining mechanism includes a degradable and/or erodible material such as a water soluble material, optionally with one or more coatings of one or more enteric materials. The degradable and/or erodible material is designed to lose its mechanical strength in the presence of moisture (e.g., liquid present in the GI tract).

Generally, an enteric material erodes after being swallowed, e.g., in the small intestine or in the large intestine. In some embodiments, the degradable and/or erodible material is coated with an enteric material that limits the amount of moisture or fluid reaching the degradable and/or erodible material, whereby the degradable and/or erodible material is able to resist a trigger load, for example, for at least two hours at a pH of 1.1. In certain embodiments, the enteric material breaks down to release a trigger load after being exposed to a pH of 1.1 for two hours followed by exposure to a pH of 6.8 for 10, 20, 30, 40, 50, 60 or more minutes.

An enteric material can be in the form of one or more coatings at varying coating weights (e.g., one or more spray coatings and/or one or more dip coatings) on a degradable and/or erodible material such as a water soluble material. For example, in some embodiments, compared to the weight of the degradable and/or erodible material, the coating weight can be 5%, 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, 50%, 55% or more. In general, the coating weight can be selected as desired, e.g., based on the intended use of the ingestible device. For example, the coating weight can be selected to select a desired location and/or time for the degradable and/or erodible material to degrade and/or erode to a sufficient extent to trigger delivery of the dispendable substance from the ingestible device.

Desirably, the degradable and/or erodible material is sufficiently strong enough to resist the trigger load when dry, but also capable of sufficiently weakening to release the trigger load when the degradable and/or erodible material is exposed to an aqueous environment for a desired period of time, such as, for example, at least two minutes, e.g., at least 5, at least 10, at least 20, at least 30, at least 40, at least 50, at least 60, at least 70, at least 80, at least 90, at least 100, at least 110, at least 120, at least 130, at least 140, at least 150, or at least 160 minutes.

In some embodiments, a triggering mechanism has a density of from about one g/cm³ to about 3 grams/cm³ (e.g., from about 1.3 g/cm³ to about 2 g/cm³).

In certain embodiments, a triggering mechanism is from about 1 mm to about 5 mm thick (e.g., from about 1 mm to about 2 mm thick).

In some embodiments, a coating of enteric material has a density of from about 0.5 mg/cm² to 20 mg/cm² (e.g., from about 2 mg/cm² to about 6 mg/cm²).

Examples of degradable and/or erodible materials include polyethylene glycol (PEG) and Isolmalt. In some embodiments, a degradable and/or erodible material includes one or more diluents/fillers, one or more binders, and/or or more disintegrants. Examples of diluents/fillers include lactose, starch, mannitol, microcrystalline cellulose, carboxymethyl cellulose, and dicalcium phosphate. Examples of binders include povidone, hypromellose, hydroxypropyl cellulose, copovidone, and microcrystalline cellulose. Examples of disintegrants include crospovidone, croscarmellose sodium (SD-711), sodium starch glycolate, and low-substituted hydroxypropyl cellulose. Optionally, a degradable and/or erodible material can include a lubricant, such as, for example, magnesium stearate.

As an example, a degradable and/or erodible material includes starch (e.g., StarTab grade from Colorcon, Starch 1500 grad from Colorcon), microcrystalline cellulose (e.g., Vivapur 102 grade from JRS Pharma), croscarmellose sodium (e.g., Ac-di-sol SD-711 grade from FMC Biopolymer), and magnesium stearate (e.g., Ligamed MF-2-V grade from Giusto Faravelli), and optionally further includes talc (e.g., PSD<75 μm grade from Acros), enteric methacrylate polymer (e.g., FL30 D-55 grade from Evonik), and HPMC polymer sub coat (e.g, Opadry 03K19229 grade from Colorcon). As an example, a degradable and/or erodible material can include Starch 1500 (e.g., 49.6% w/w), microcrystalline cellulose 102 Starch (e.g., 49.6% w/w); and croscarmellose sodium SD-711 (e.g., 0.5% w/w); and magnesium stearate (e.g., 0.26% w/w). As a further example, a degradable and/or erodible material can include Startab (e.g., 49.6% w/w), microcrystalline cellulose 102 Starch (e.g., 49.6% w/w); and croscarmellose sodium SD-711 (e.g., 0.5% w/w); and magnesium stearate (e.g., 0.26% w/w). As another example, a degradable and/or erodible material can include Starch 1500 (e.g., 48.9% w/w), microcrystalline cellulose 102 Starch (e.g., 48.9% w/w); croscarmellose sodium SD-711 (e.g., 2% w/w); and magnesium stearate (e.g., 0.26% w/w). As further example, a degradable and/or erodible material can include Startab (e.g., 49.6% w/w), microcrystalline cellulose 102 Starch (e.g., 49.6% w/w); croscarmellose sodium SD-711 (e.g., 2% w/w); and magnesium stearate (e.g., 0.26% w/w). As another example, a degradable and/or erodible material can include dicalcium phosphate (e.g., 48.9% w/w), microcrystalline cellulose 102 Starch (e.g., 48.9% w/w); croscarmellose sodium SD-711 (e.g., 2% w/w); and magnesium stearate (e.g., 0.25% w/w). As a further example, a degradable and/or erodible material can include dicalcium phosphate (e.g., 33.25% w/w), microcrystalline cellulose 102 Starch (e.g., 33.25% w/w); mannitol (e.g., 33.25% w/w); and magnesium stearate (e.g., 0.25% w/w).

Examples of enteric materials coated on a degradable and/or erodible material include: spray coated Eudragit FL 30 D-55 (e.g., 12 mg/cm² direct spray coated Eudragit FL 30 D-55 on a water soluble material); dip coated Eudragit L 100 D-55 (e.g., 4 mg/cm² Eudragit L 100 D-55 dip coated onto an HPMC capsule cap); and spray coated Eudragit FL 30 D-55 (e.g., 9 mg/cm² Eudragit FL 30 D-55 direct spray coated on a water soluble material; 6 mg/cm² Eudragit FL 30 D-55 direct spray coated on a water soluble material).

Triggering Mechanism

In some embodiments, the ingestible device comprises a triggering mechanism. In some embodiments, a triggering mechanism is configured to cause the dispensable substance within the fluid volume to be released under one or more triggering conditions. In some embodiments, a triggering mechanism initiates a drive force generator. In some embodiments, a triggering mechanism incorporates a mechanical feature like a restraining mechanism. As an example, one or more restraining elements degrade and/or erode in the presence of certain GI tract conditions (e.g., pH greater than 5), thereby triggering a drive force generator, such as a compressed spring. As another example, a spring may have a piercing element that pierces a cylinder with compressed gas, whereby the released gas acts as a force applied to a dispensable substance. In certain embodiments, a triggering mechanism incorporates an electrical feature. For example, an enteric coating degrades and/or erodes in the presence of certain GI tract conditions (e.g., pH greater than 5), thereby exposing conductors to intestinal fluid, which acts as a liquid conductor to triggering the drive force generator. In some embodiments, a triggering condition relates to a condition of the GI tract. In some embodiments, the condition of the GI tract comprises at least one condition selected from the group consisting of temperature, pH, presence of one or more enzymes, and time. In some more particular embodiments, the condition of the GI tract is a pH of greater than 5. In certain embodiments, the triggering mechanism is configured so that the release mechanism is autonomously triggered (e.g., due to degradation, dissolution and/or erosion of the restraining mechanism due to conditions in the GI tract).

In some embodiments, a restraining element can include one or more small molecule therapeutic agents, e.g., one or more small molecule therapeutic agents as disclosed herein. In certain embodiments, a small molecule therapeutic agent contained in the restraining mechanism can be the same as a therapeutic agent contained in the dispensable substance. In some embodiments, a small molecule therapeutic agent contained in the restraining mechanism can different from a therapeutic agent contained in the dispensable substance. In certain embodiments, the restraining mechanism includes multiple small molecule therapeutic agents, and the dispensable substance contains the same therapeutic agents. In some embodiments, the restraining mechanism includes multiple small molecule therapeutic agents, and the dispensable substance contains one or more different therapeutic agents. In certain embodiments, the dispensable substance includes a therapeutic agent that is capable of treating a certain condition, and a small molecule therapeutic agent included in the restraining element is capable of treating the same condition. In some embodiments, the dispensable substance includes a therapeutic agent that is capable of treating a certain condition, and a small molecule therapeutic agent included in the restraining element is capable of treating a different condition. In certain embodiments, the dispensable substance includes a therapeutic agent that is capable of treating a certain condition, and the small molecule therapeutic agent included in the restraining element is capable of treating the same condition and at least one different condition. In some embodiments, a small molecule therapeutic agent included in the restraining element is capable of treating a certain condition, and the dispensable substance includes a therapeutic agent that is capable of treating at least one different condition. Other combinations are possible.

In general, the initial gas pressure within the gas cylinder (gas pressure before the gas cylinder is implemented as a force generator) is appropriate to provide the desired internal pressure. Typically, the initial gas pressure in the cylinder is at least about 500 psig (e.g., at least about 600 psig, at least about 700 psig, at least about 750 psig, at least about 800 psig, at least about 850 psig, at least about 900 psig) and/or at most about 1,200 psig (e.g., at most about 1,100 psig, at most about 1,000 psig, at most about 950 psig, at most about 900 psig). In some embodiments, the initial gas pressure within the gas cylinder is from about 500 psig to about 1,200 psig (e.g., from about 600 psig to about 1,100 psig, from about 700 psig to about 1,000 psig, from about 750 psig to about 950 psig, from about 800 psig to about 950 psig, from about 850 psig to about 950 psig).

The burst pressure of the gas cylinder (the minimum pressure at which the gas cylinder bursts) is usually based on the desired initial gas pressure within the gas cylinder. For initial gas pressures noted in the preceding paragraph, the burst pressure of the gas cylinder can be at least about 2,800 psig (e.g., at least about 2,900 psig, at least about 3,000 psig, at least about 3,100 psig, at least about 3,200 psig, at least about 3,300 psig, at least about 3,400 psig, at least about 3,500 psig, at least about 3,600 psig) and/or at most about 4,500 psig (e.g., at most about 4,400 psig, at most about 4,300 psig, at most about 4,200 psig, at most about 4,100 psig, at most about 4,000 psig, at most about 3,900 psig, at most about 3,800 psig). In some embodiments, the burst pressure of the gas cylinder is from about 2,800 psig to about 4,500 psig (e.g., from about 2,900 psig to about 4,400 psig, from about 3,000 psig to about 4,300 psig, from about 3,100 psig to about 4,200 psig, from about 3,200 psig to about 4,100 psig, from about 3,100 psig to about 4,000 psig, from about 3,200 psig to about 3,900 psig, from about 3,300 psig to about 3,800 psig, from about 3,400 psig to about 3,800 psig, from about 3,500 psig to about 3,800 psig, from about 3,600 psig to about 3,800 psig, from about 3,700 psig to about 3,800 psig).

Generally, the gas within the gas cylinder can be a single gas or a mixture of two or more gases. Exemplary gases include air, nitrogen, oxygen, carbon dioxide, hydrofluorocarbon gases, and noble gases (e.g., helium, neon, argon, krypton, xenon). In some embodiments, the gas within the gas cylinder is a mixture of gases that include helium (e.g., nitrogen/helium mixture, argon/helium mixture). Optionally, such gas mixtures include at most about 5% helium. The presence of helium in a gas mixture can allow for leak checking the gas cylinder based on the presence of helium gas adjacent the exterior of the gas cylinder.

In general, the gas cylinder may be made of any appropriate and/or desired material. Examples include metal, plastic, and/or composite materials. In some embodiments, the gas cylinder is made of stainless steel or galvanized steel. In certain embodiments, the gas cylinder may be made from a material which is itself prepared by a process that includes drawing, stamping, machining, casting, molding, and/or the like (e.g., deep drawing from sheet metal). In some embodiments, the gas cylinder may be made of a ceramic, an alloy, aluminum and/or titanium.

In some embodiments the gas cylinder includes a breakable seal (e.g., a membrane) which is broken via an element (e.g., a piercer) when the gas cylinder is being used as a force generator, as described in more detail below. Typically, the breakable seal is part of an end cap of the gas cylinder. The end cap and/or the breakable seal can be formed of one or more of the materials noted in the preceding paragraph. Breaking the breakable seal may involve, for example, tearing a portion of the breakable seal and/or puncturing a portion of the breakable seal. More generally, breaking the breakable seal means to modify the seal in a manner such that the breakable seal is no longer able to confine the gas within the gas cylinder. In general, the breakable seal is made of a material that has at least a region that is relatively thin and/or that is configured (e.g., scored) to break. Optionally, the entire barrier is relatively thin. As an example, the barrier may have a relatively thin perimeter with a relatively thick portion within the perimeter (e.g., central portion) so that, when the element (e.g., piercer) applies an appropriate force, the relatively thin portion of the breakable seal breaks. As another example, the barrier may have an inner (e.g., central) portion surrounded by a portion that is scored so that, when the element (e.g., piercer) applies an appropriate force, the scored portion of the breakable seal breaks. In some embodiments, the breakable seal has a substantial constant thickness and has a portion that is configured (e.g., scored) to break when the element (e.g., piercer) applies an appropriate force. In general, such scoring can be configured as desired. As an example, scoring can be configured as a series of parallel lines. As another example, scoring can be configured as a grid (cross-hatched). As a further example, scoring can be configured as a plurality of dots (e.g., equally spaced dots).

In some embodiments, the element (e.g., piercer) has a contact point on the breakable seal. Optionally, the contact point is concentrated in a relatively small local area. For example, the piercer may be a needle or a thin rod element that is cut at an angle to initially generate a single point contact. Relative to the breakable seal, the point of initial contact may be on-center or off-center. Having the point of initial contact off-center relative to the breakable seal can result in a reduced force applied by the element (e.g., piercer). In embodiments where the modified (e.g., scored) region of the breakable seal is off-center, placing the element (e.g., piercer) off-center means that the contact point is closer to the modified (e.g., thinner scored region) of the breakable seal at the contact point of the element (e.g., piercer) with the breakable seal. In certain embodiments where the modified (e.g., scored) region of the breakable seal is a circle, the element (e.g., piercer) can be configures to that its contact point with the breakable seal is near one point on the circle. In general, the closer this contact point is to the modified region of the breakable seal, the lower the force of the element (e.g., piercer) used to break the breakable seal. To create a relatively fast release, the modified (e.g., score) portion of the breakable seal desirably fails over substantially most of the modified region, e.g., the diameter of the circle when the modified region is a scored region shaped as a circle. In some embodiments, the closer the contact point is to the center of the scored circle, the more likely that the seal fails on the entire circumference of the scored circle. In such embodiments, it is typically desirable to have the contact point of the element (e.g., piercer) be near the circle but not on it. Optionally, the contact point can be move inwards to get fast release properties. Optionally, a wider footprint for the initial contact of the element (e.g., piercer) may be implemented in some embodiments. For example, the contact point can be a sector of an arc placed near a circular score of the breakable seal. This can encourage failure of the breakable seal over a larger sector of the score region, which can yield faster gas escape.

In some embodiments, before the gas cylinder is used as a force generator, the element (e.g., piercer) is not in contact with the breakable seal. In certain embodiments, before the gas cylinder is used as a force generator, the element (e.g., piercer) may be in contact with the breakable seal such that the element (e.g., piercer) applies a relatively low pressure to the breakable seal. This pressure may be, for example, at least about one Newton (e.g., at least about two Newtons, at least about three Newtons, at least about four Newtons, at least about five Newtons) and/or at most about 15 Newtons (e.g., at most about 14 Newtons, at most about 13 Newtons, at most about 12 Newtons, at most about 11 Newtons, at most about 10 Newtons). In some embodiments, this pressure is from about one Newton to about 15 Newtons.

Generally, to cause the gas in the gas cylinder to be released from the gas cylinder, the element (e.g., piercer) applies a relatively high pressure to the breakable seal. This relatively high pressure may be, for example, at least about five Newtons (e.g., at least eight Newtons, at least about 10 Newtons, at least about 15 Newtons) and/or at most about Newtons (e.g., at most about 35 Newtons, at most about 30 Newtons, at most about 25 Newtons). In some embodiments, the relatively high pressure may be from about five Newtons about 35 Newtons.

Examples of gas cylinders, including those with an end cap and/or breakable seal, are disclosed, for example, in US 2017/0258583, the entire disclosure of which is incorporated by reference herein.

In some embodiments, the element (e.g., the piercer) is coupled to an actuator in an actuator assembly. In some embodiments, the actuator assembly has a total length of less than about 10 mm (e.g., less than about 9 mm, less than about 8 mm, less than about 7 mm, less than about 6 mm, less than about 5 mm, less than about 4 mm, less than about 3 mm, less than about 2 mm). In some embodiments, the actuator is a spring (e.g., a wave spring). In some embodiments, the spring has a compressed length of less than about 5 mm, less than about 4 mm, less than about 3.5 mm, less than about 3 mm, less than about 2.5 mm). In some embodiments, the spring has a stroke length of less than about 0.8 mm (e.g., less than about 0.7 mm, less than about 0.6 mm, less than about 0.5 mm, less than about 0.4 mm, less than about 0.3 mm).

In some embodiments, the element (e.g., the piercer) is moved relatively quickly when applying the relatively high force to the breakable seal. In certain embodiments, the element (e.g., the piercer) is moved relatively slowly when applying the relatively high force to the breakable seal. In some embodiments, to break the breakable seal, using a lower speed for moving the element (e.g., piercer) allows for use of a lower force compared to the force used to break the breakable seal when the element (e.g., piercer) moves at a higher speed.

In some embodiments, the element (e.g., piercer) moves relative to the gas cylinder. In certain embodiments, the gas cylinder moves relative to the element (e.g., piercer). For example, the gas cylinder can be coupled to an actuator which causes the gas cylinder to move.

In some embodiments of any of the devices or methods described herein, the releasing of the therapeutic is triggered by one or more of: a pH in the jejunum of about 6.1 to about 7.2, a pH in the mid small bowel of about 7.0 to about 7.8, a pH in the ileum of about 7.0 to about 8.0, a pH in the right colon of about 5.7 to about 7.0, a pH in the mid colon of about 5.7 to about 7.4, or a pH in the left colon of about 6.3 to about 7.7, such as about 7.0.

Drive Force Generator

The drive force generator is configured to provide the requisite force to the dispensable substance such that, when the restraining mechanism is removed, the dispensable substance is delivered from the ingestible device as desired. The drive force generator can apply force using different mechanisms, including, for example, a compressed gas, a gas generated by chemical reaction, a spring, a liquid-gas mixture, an impact ram, a sudden expansion caused by a controlled exothermic reaction, or the like. When the drive force generator is a spring, the spring can have one or more of the following properties: the outer diameter of the spring is smaller than the inner diameter of the ingestible device; the compressed length of the spring is minimized to leave more space for dispensable substance; the spring is of a conical shape, potentially with a reduction in the solid length of the spring; the free length of the spring is maximized and larger than the free length of the inner cavity of the ingestible device to ensure an acceptable driving pressure is provided throughout the entire time step of delivery; and the spring rate is large enough to provide acceptable pressure from the beginning until the end of delivery of the dispensable substance. Examples of springs include parallel springs, wave springs and conical springs. Examples of chemical reactants include an airbag inflator, a hydrogen cell (e.g., a Varta hydrogen cell), sodium bicarbonate and acid (e.g., alka seltzer and water on board the ingestible device, alka seltzer and GI tract fluid). Examples of compressed gas include a gas charged within the ingestible device, and a container (e.g., cylinder) of compressed gas. In some embodiments, the compressed gas is a gas cylinder from Picocyl. Exemplary gas cylinders are disclosed, for example, in US 2017-0258583, which is incorporated by reference herein. An example of a liquid-gas mixture is liquid nitrogen/HFA (hexafluoroacetone)/propane. An example of an impact ram is a two-phase spring/ram. Other examples of drive force generators include a wax actuator, heat generated by electric power (Peltier effect-based mechanism), and a mechanical puncture of tissue followed by delivery.

Drive Coupling

In general, the drive force coupling transfers a force from the drive force generator to the dispensable substance. Examples of a drive coupling include a piston and a membrane. Examples of membranes include balloons and elastomeric materials. An example of a piston is an O-ring sealed piston. In some embodiments, a piston is provided by a gas cylinder, e.g., with added O-rings or a custom housing. In some embodiments, a drive coupling is a vein, such as a rotating vein. In certain embodiments, a drive coupling is a double piston configured to counteract cap impact. In certain embodiments, a drive coupling is a collapsing bag, such as a collapsing foil bag. In some embodiments, a drive coupling is a collapsing bellows.

Storage Reservoir

In some embodiments, an ingestible device includes a storage reservoir configured to store a dispensable substance. In some embodiments, the storage reservoir stores the dispensible substance. In some embodiments, the storage reservoir is completely disposed within the housing.

FIG. 2 is a schematic representation of an ingestible device 200 which includes a housing 202, a fluid volume 204 containing a dispensable substance, a nozzle 206 with a nozzle opening 208, a restraining mechanism 210, a triggering mechanism 212, a drive force generator 214 and drive coupling 216. During use, ingestible device 200 is swallowed by a subject and traverses the GI tract. At an appropriate location, the triggering mechanism 212 is triggered, allowing the drive force generator to apply pressure to the drive coupling 216, which then applies pressure to the fluid volume such that at least some of the dispensable substance is delivered out of fluid volume 204, through the nozzle 206, and out of the device 200 via the nozzle opening 208. In some embodiments, the internal pressure is applied, even before the triggering mechanism 212 is triggered. As an example, at an appropriate location, the triggering mechanism 212 is triggered, allowing the drive coupling 216 to apply pressure to the fluid volume 204. In certain embodiments, the internal pressure is not applied until the triggering mechanism 212 is triggered.

Device for Trans-Epithelial Delivery

Generally, trans-epithelial delivery can be achieved at any desired location within the GI tract of a subject.

FIG. 3 shows cross sectional views of a representative ingestible device 400 for trans-epithelial delivery, schematically illustrating certain parameters and components of action for the device 400. These include a drive force generator 42 which applies a force (resulting in an internal pressure) to a drive coupling 44. The drive coupling 44 transfers force from the force generator 42 to a fluid volume 46 containing a dispensable substance (e.g., a liquid, a suspension). The force applied to the fluid volume 46 by the drive coupling 44 generates pressure in the fluid volume 46 (fluid pressure). The pressure in the fluid volume 46 generates high-speed flow through an open nozzle 48 to produce a jet 50 of fluid at the nozzle outlet 52 that has a nozzle diameter 72 and the nozzle has a nozzle length 74.

During trans-epithelial delivery, the fluid jet 50 has a jet stable length 54 that is sufficient for the fluid jet 50 to travel across a nozzle stand-off distance 56 to reach the interface of the lumen of the GI tract and the surface of the GI tract facing the lumen. Ultimately, the fluid (e.g., liquid, suspension) impacts the mucosal layer of the GI tract (e.g., the epithelial layer and any mucus that may be present on the epithelial layer) as a stable stream of fluid with little breakup into a spray and is deposited in the submucosal and/or the mucosal tissue 58. That is, between the nozzle outlet 52 and the site of impact at the mucosa, the jet 50 has a jet diameter 76 that can vary in the manner discussed above with respect to the average jet diameter.

The fluid volume 46 experiences a peak fluid pressure 60 that generates the fluid jet 50 that exits the device 40 with a peak jet velocity, and impacts the interface of the lumen of the GI tract and the surface of the GI tract facing the lumen with a peak jet power, peak jet pressure and peak jet force. One of ordinary skill in the art recognizes that these three parameters are interconnected.

The pressure in the fluid volume 46 decreases during delivery so that the fluid pressure during delivery 70 varies, as does the jet power, jet force, and jet pressure. The fluid pressure during delivery 70 maintains the fluid jet 50 at sufficient jet impact force during delivery to continue fluid (dispensable substance including one or more therapeutic agents) delivery from the fluid volume 46 into the submucosal and/or mucosal tissue 58. The surrounding tissue can then absorb the delivered therapeutic agents for systemic delivery of the therapeutic agent.

Even prior to when the subject swallows the ingestible device, the drive coupling 44 transmits force from the force generator 42 to the fluid volume 46. The drive coupling 44 is prevented from moving by a restraining mechanism 80 (e.g., a pin or plug that selectively degrades and/or selectively erodes) until movement of the drive coupling is triggered by a triggering mechanism, and/or an opening becomes open.

FIG. 4 shows an exemplary process flow chart 400 for use of an ingestible device in which pressure is not applied to the dispensable substance before the subject swallows the ingestible device. The process beings at step 402, when the patient swallows the ingestible device. In step 404, a triggering condition (e.g., pH, change in pH, presence of certain enzyme, concentration of certain enzyme) is met in the GI tract, thereby triggering the drive force generator. In step 406, the drive force mechanism applies pressure to the dispensable substance, resulting delivery of a jet of the dispensable substance from the ingestible device for each opening. In step 408, the jet has a sufficient jet stable length for the jet to impact the GI tissue of the subject. In step 410, the peak jet power of the jet is sufficient to achieve trans-epithelial delivery of the therapeutic agent contained in the dispensable substance. In step 412, the fluid pressure of the dispensable substance decreases during delivery but is sufficiently so that the peak jet power continues to be sufficient to achieve trans-epithelial delivery of the therapeutic agent contained in the dispensable substance.

The ingestible device also includes coverings 522 over the nozzle openings, a spring 524, a gas cylinder 504 having a breakable seal, a piston 506 (e.g., made of a COC), a piercer 512, and an O-ring 526. Nozzle covering 522 can be an integral nozzle cover for gastric protection and can be softened after the ingestible device 500 is ingested, e.g., by gastric fluids, such that the coverings 522 dissolve/degrade and expose the nozzles 502. In some embodiments, O-ring 526 may be lubricated. Similarly, any O-ring disclosed elsewhere herein can optionally be lubricated.

The ingestible device 500 also includes a collar-shaped trigger element 528 which is the triggering mechanism. Although FIG. 5B depicts the trigger element 528 as being collar-shaped, other shapes may be used. In general, the trigger element 528 can have any appropriate shape. Examples of shapes for the trigger element include a complete annulus, an annulus partitioned into two pieces. In some embodiments, the trigger element includes two or more sectors of an annulus with gaps between the sectors. In some embodiments, such a design can increase surface exposure to the environment (e.g., water environment) to promote degradation. For example, FIG. 5C shows a split two-piece collar, e.g., separate assembly modules 530 and 532 which are assembled to form ingestible device 500.

FIGS. 6A-6C, respectively, show view of an ingestible device 600 as assembled, an exploded of the ingestible device 600, and aspects of a process of assembly for the ingestible device 600. The ingestible device 600 may be used for trans-epithelial delivery or for other forms of delivery as appropriate as discussed elsewhere herein. Ingestible device 600 includes, a nozzle 602, gas cylinder 604, piston 606 seal 608, pierce pin 610, and piercer 612. A removable cap 614 can be secured over a portion of the ingestible device 600 and removed prior to swallowing. The ingestible device is configured so that the dispensable substance 616 in the device is not under pressure when the subject swallows the ingestible device. The ingestible device has two housing parts, a primary container 618 and a secondary container 620. The primary container 618, which includes a fluid volume containing the dispensable substance, can be formed of a cyclic olefin copolymer (COC), such as a molded COC, or any other appropriate material as disclosed elsewhere herein. The primary container 618 includes nozzles 602 with nozzle openings. In some embodiments, the nozzle lengths are about equal to the primary container wall thickness. Exemplary nozzle lengths include about 0.3 mm, about 0.4 mm, about 0.5 mm, about 0.6 mm, about 0.7 mm, about 0.8 mm, about 0.9 mm, and about 1.0 mm. In some embodiments, the nozzle lengths are about 0.7 mm. The ingestible device 600 also includes coverings 622 over the nozzle openings, a spring 624, a gas cylinder 604 having a breakable seal 608, a piston 606 (e.g., made of a COC, or another appropriate material), a two-part piercer, and an O-ring 626. The ingestible device also includes a collar-shaped trigger element 628 which is the triggering mechanism, which can be made of any appropriate material as discussed elsewhere herein. Although FIGS. 6A-6C depict the trigger element 628 as being collar-shaped, other shapes may be used, as disclosed elsewhere herein.

The device shown in FIGS. 6A-6C has an enhanced piston stabilization length 634 (e.g., about 2 millimeters). The device shown in FIGS. 6A-6C has a metal spring slider 636, which can enhance space efficiency. The device shown in FIGS. 6A-6C has a piercer slider 638 (e.g., a metal piercer slider) that bottoms out on the spring housing during assembly. This can enhance space efficiency. In the device shown in FIGS. 6A-6C, the two part piercer reduces (e.g., removes) tolerances when manufacturing the trigger element from the piercer clearance with the gas cylinder. In the device shown in FIGS. 6A-6C, the piercer seal 640 (e.g., O-ring) has a relatively small diameter, which can enhance stability and/or reduce resistive pressure build up along its stroke length. In the device shown in FIGS. 6A-6C, the spring 624 has a tapered end coil 642, which can enhance the maximum force potential. In some embodiments, a wave spring may be used. FIGS. 6A-6C shows a gas tight seal 644 (e.g., an ultranonic weld). FIGS. 6A-6C also shows a gas cylinder retention feature 646.

In addition, the ingestible device includes a removable cap 614 which is removed (e.g., by the user) before the ingestible device is swallowed. When the device 600 is swallowed by the subject, the trigger element 628 prevents the dispensable substance 616 in the fluid volume from being under pressure by holding the spring 624 and the piercer 612 in place. When the device reaches the appropriate location in the GI tract, the trigger element 628 at least partially erodes, degrades and/or dissolves (e.g., due to pH, change in pH, presence of certain enzyme, and/or concentration of certain enzyme), and the trigger element 628 is no longer sufficient to hold back the pressure from the spring 624. In some embodiments, the trigger element 628 at least partially erodes, degrades and/or dissolves in the presence of water. In such embodiments, the trigger element may include a covering of a thin film of material that preferentially degrades due to, for example, a change in pH and/or presence of enzyme. The spring 624 forces the pierce pin 610 of piercer 612 into the breakable seal 608, causing the breakable seal to break. This causes gas at elevated pressure to leave the cylinder 604, causing an elevated pressure to bear against the piston 606 and apply pressure to the fluid volume 616. This causes the coverings 622 of the nozzle openings, which are made of a relatively low mechanical strength material (e.g., a foil or a film), to break so that the dispensable substance is delivered out of the nozzle openings in the form of a jet. In certain embodiments, the covering 622 of the nozzle openings are made of a material that erodes, degrades and/or dissolves in the presence of, for example water or elevated pH (e.g., an enteric band or band of water soluble polymer material). The coverings may be partially or completely displaced from the capsule at the time the trigger element actuates. This results in in trans-epithelial delivery of the therapeutic agent contained in the dispensable substance.

FIG. 6C shows aspects of a process for the assembly of the ingestible device, e.g., separate assembly modules 630 and 632 which are assembled to form ingestible device 600. FIG. 6C depicts that the primary container, combined with the cap and nozzle coverings, has the dispensable substance added thereto, followed by adding the piston. This may be done in aseptic environment or other environment appropriate for drug filling and separate from the environment where the mechanical drive assembly is constructed. The other housing part and its components are assembled in a clean environment with the piercer held in place by the trigger element. The gas cylinder 604 is held in place by components of this assembly, including the assembly housing which includes features for locating the gas cylinder in its proper position in the assembled ingestible device. Locating and mounting of the gas cylinder may be aided by the formation of a mounting feature integral to the gas cylinder component such as a flange.

FIGS. 7-13 show various views of an ingestible device 700 and/or aspects of the ingestible device 700. As is apparent, the delivery mechanism of the ingestible device 700 is shown as having a design substantially similar to the device shown in FIG. 5 , although, more generally, the ingestible device 700 depicted in FIGS. 7-13 can have a delivery mechanism as described elsewhere herein.

Ingestible device 700 includes a gas cylinder 716, a union ring 708, an o-ring 732, an enteric trigger 726, a piercer 720, a spring 724, a spring retention cup 722, a retention element 728, a drug housing 704, a drive housing 706, and a piercer retainer 724.

The ingestible device 700 has two chambers 710 a, 710 b, each containing a dispensable substance. The chambers are separated by a separator 705, such as a rib, which prevents the dispensable substance in one chamber from entering another chamber, e.g., from 710 a to 710 b and vice versa. In addition, the ingestible device 700 includes a face seal 707 that seals the separator. The ingestible device also has two pistons 718 a, 718 h, one for each chamber. Each chamber 710 a, 710 b has at least nozzle 702 for delivering the dispensable substance from the chamber to an exterior of the ingestible device 700. In general, the dispensable substance in one chamber, e.g., chamber 710 a can be the same as or different from the dispensable substance in the other chamber, e.g., chamber 710 b. While shown as having two chambers 710 a, 710 b, the disclosure is not limited in this sense. More generally, the ingestible device 700 can have as many chambers as desired (e.g., two chambers, three chambers, four chambers, five chambers, six chambers, seven chambers, eight chambers, nine chambers, 10 chambers, more than 10 chambers). In general, each chamber 710 a, 710 b will have a corresponding piston 718 a, 718 b, and there will be a separator 705 between adjacent chambers. In some embodiments, each chamber has the same internal volume. In certain embodiments, different chambers can have different volumes. Combinations of such embodiments are also possible.

In some embodiments the disclosure provides an ingestible device that includes an element 712 (e.g., covering) having a first state in which the element 712 at least partially covers the nozzle opening of nozzle 702 in the housing 704 and a second state in which the element 712 does not cover the nozzle opening in the housing 704, where the ingestible device 700 is configured so that, when the drive force coupling (e.g., piston 718 a, 718 b) moves, the element 712 moves from its first state to its second state. In certain embodiments, the element 712 conforms to an inner radius of the housing 704, is flexible and/or includes a cylindrical portion. In some embodiments, the element 712 is removable from the ingestible device 700 (e.g., when the element 712 is in its second state, the element 712 is removed from the ingestible device). Such a removable element 712 can be, for example, a cap. Optionally, the element 712 moves can move synchronously with the drive force coupling, e.g., pistons 718 a, 718 b. In some embodiments, when the drive force coupling moves a distance, the element 712 moves the same distance. The ingestible device can include a seal 718 (e.g., an O-ring) that mechanically coupled (e.g., sealed) with the drive force coupling and element 712. With this arrangement, the seal 718 can be configured to cause the movement of the drive force coupling to result in the movement of the element 712.

FIGS. 14-18 show an ingestible device 1400 which contains a dispensable substance that is not under pressure when the subject swallows the ingestible device. In FIG. 14 , the jet opening 1402 is depicted is covered, and in FIG. 15 the jet opening 1402 is uncovered.

FIGS. 16 and 17 show the ingestible device 1400 in more detail. The ingestible device 1400 has housing parts 1404 and 1406 connected by a union ring 1408 and with a fluid volume 1410 containing a dispensable substance, opening 1402, and a jet covering 1412, e.g., a cylindrical sleeve made of a flexible material which is able to conform to an inside radius of the housing 1406 which slides to open or seal the opening 1402, a spring 1414, a gas cylinder 1416, a piston 1418, a piercer 1420, and an O-ring 1432. Gas cylinder 1416 is retained by retention element 1428. A seal 1430 forms a gas seal between the piercer 1420 and the housing 1404. A spring retention cup 1422 retains the spring-loaded piercer 1420. A piercer retainer 1424 holds the piercer 1420 in place with an enteric trigger 1426 that retains the piercer retainer in place until it dissolves and used as the triggering mechanism. When the device 1400 is swallowed by the subject, the enteric trigger 1426 prevents the dispensable substance in fluid volume 1410 from being under pressure by holding the spring 1414 and the piercer 1420 in place. When the device 1400 reaches the appropriate location in the GI tract, the enteric trigger 1426 degrades and/or dissolves (e.g., due to pH, change in pH, presence of certain enzyme, and/or concentration of certain enzyme) that the pierce pin retainer 1424 is no longer sufficient to hold back the pressure from the spring 1414. The spring 1414 forces the piercer 1420 into the gas cylinder 1416, puncturing the gas cylinder 1416 and causing gas at elevated pressure to leave the cylinder 1416. This causes the gas cylinder 1416 to press against the piston 1418 and apply pressure to the fluid volume 1410. The piston provides friction to slide the jet covering 1412 open exposing the jet openings 1402 such that the dispensable substance is delivered out of the jet opening 1402 in the form of a jet. This results in trans-epithelial delivery of the therapeutic agent contained in the dispensable substance. FIG. 17 shows the embodiment of the ingestible device 1400 in which the jet covering 1412 is slide open to expose the jet openings 1402.

Typically, the ingestible device 1400 is used in trans-epithelial delivery. However, the ingestible device 1400 may be used for either epithelial delivery or topical delivery. Appropriate parameters for the different types of delivery are provided elsewhere herein.

In some embodiments, the housing of the ingestible device 1400 has a diameter from about 9.5 mm to about 10.5 mm (e.g., from about 9.8 mm to about 10 mm), a length from about 23 mm to about 26.5 mm (e.g., from about 23.3 mm to about 26.1 mm), a wall thickness from about 0.4 mm to about 0.6 mm (e.g., about 0.5 mm), a fluid volume from about 425 μL to about 600 μL (e.g., from about 450 μL to about 585 μL), and/or a gas volume in the gas cylinder 1416 from about 150 μL to about 175 μL (e.g., about 160 μL). FIG. 18 shows the ingestible device 1400 where the jet covering 1412 conforms along a radius of the ingestible device 1400.

FIGS. 19 and 20 show an ingestible device 1900 in its closed and open states, respectively. The ingestible device 1900 contains a dispensable substance that is not under pressure when the subject swallows the ingestible device. The ingestible device 1900 has housing parts 1904 and 1906 connected by a union ring 1908 and with a fluid volume 1910 containing a dispensable substance, a spring 1914, a gas cylinder 1916, a piston 1918, a piercer 1920, and an O-ring 1932. Gas cylinder 1916 is retained by retention element 1928. A seal 1930 forms a gas seal between the piercer 1920 and the housing 1906. A spring retention cup 1922 retains the spring-loaded piercer 1920. A piercer retainer 1924 holds the piercer 1920 in place with an enteric trigger 1926 that retains the piercer retainer in place until it dissolves and used as the triggering mechanism. When the device 1900 is swallowed by the subject, the enteric trigger 1926 prevents the dispensable substance in fluid volume 1910 from being under pressure by holding the spring 1914 and the piercer 1920 in place. When the device 1900 reaches the appropriate location in the GI tract, the enteric trigger 1926 degrades and/or dissolves (e.g., due to pH, change in pH, presence of certain enzyme, and/or concentration of certain enzyme) that the piercer retainer 1924 is no longer sufficient to hold back the pressure from the spring 1914. The spring 1914 forces the piercer 1920 into the gas cylinder 1916, puncturing the gas cylinder 1916 and causing gas at elevated pressure to leave the cylinder 1916. This causes the gas cylinder 1916 to press against the piston 1918 and apply pressure to the fluid volume 1910. The piston provides friction to cause the cap 1934 to open/deploy such that the dispensable substance is delivered out of the volume 1910. This results in release of the therapeutic agent into the GI tract of the subject.

In some embodiments, the housing of the ingestible device 1900 has a diameter from about 10 mm to about 12 mm (e.g., from about 11.3 mm to about 11.5 mm), a length from about 23 mm to about 26.5 mm (e.g., from about 23.3 mm to about 26.3 mm), a wall thickness from about 0.4 mm to about 0.6 mm (e.g., about 0.5 mm), a fluid volume from about 565 μL to about 630 μL (e.g., from about 574 μL to about 623 μL), and/or a gas volume in the gas cylinder 1916 from about 150 μL to about 175 μL (e.g., about 160 μL).

In general, the ingestible device 1900 is used in topical delivery.

FIGS. 21 and 22 show an ingestible device 2100 in its closed and open states, respectively. The ingestible device 2100 contains a dispensable substance that is not under pressure when the subject swallows the ingestible device. The ingestible device 2100 has housing parts 2104 and 2106 connected by a union ring 2108 and with a fluid volume 2110 containing a dispensable substance, a spring 2114, a gas cylinder 2116, a piston 2118, a piercer 2120, and an O-ring 2132. Gas cylinder 2116 is retained by retention element 2128. A seal 2130 forms a gas seal between the piercer 2120 and the housing 2106. A spring retention cup 2122 retains the spring-loaded piercer 2120. A piercer retainer 2124 holds the piercer 2120 in place with an enteric trigger 2126 that retains the piercer retainer in place until it dissolves and used as the triggering mechanism. When the device 2100 is swallowed by the subject, the enteric trigger 2126 prevents the dispensable substance in fluid volume 2110 from being under pressure by holding the spring 2114 and the piercer 2120 in place. When the device 2100 reaches the appropriate location in the GI tract, the enteric trigger 2126 degrades and/or dissolves (e.g., due to pH, change in pH, presence of certain enzyme, and/or concentration of certain enzyme) that the piercer retainer 2124 is no longer sufficient to hold back the pressure from the spring 2114. The spring 2114 forces the piercer 2120 into the gas cylinder 2116, puncturing the gas cylinder 2116 and causing gas at elevated pressure to leave the cylinder 2116. This causes the gas cylinder 2116 to press against the piston 2118 and apply pressure to the fluid volume 2110. The piston provides friction to cause the cap 2134 to open/deploy such that the dispensable substance is delivered out of the volume 2110. This results in delivery (e.g., topical delivery) of the therapeutic agent contained in the dispensable substance.

In some embodiments, the housing of the ingestible device 2100 has a diameter from about 10 mm to about 12 mm (e.g., from about 11.3 mm to about 11.5 mm), a length from about 23 mm to about 26.5 mm (e.g., from about 23.3 mm to about 26.3 mm), a wall thickness from about 0.4 mm to about 0.6 mm (e.g., about 0.5 mm), a fluid volume from about 565 μL to about 630 μL (e.g., from about 574 μL to about 623 μL), and/or a gas volume in the gas cylinder 2116 from about 150 μL to about 175 μL (e.g., about 160 μL).

FIGS. 23 and 24 show an ingestible device 2300 in its closed and open states, respectively. The ingestible device 2300 contains a dispensable substance that is not under pressure when the subject swallows the ingestible device. The ingestible device 2300 has housing parts 2304 and 2306 connected by a union ring 2308 and with a fluid volume 2310 containing a dispensable substance, a spring 2314, a gas cylinder 2316, a piston 2318, a piercer 2320, and an O-ring 2332. Gas cylinder 2316 is retained by retention element 2328. A seal 2330 forms a gas seal between the piercer 2320 and the housing 2306. A spring retention cup 2322 retains the spring-loaded piercer 2320. A piercer retainer 2324 holds the piercer 2320 in place with an enteric trigger 2326 that retains the piercer retainer in place until it dissolves and used as the triggering mechanism. When the device 2300 is swallowed by the subject, the enteric trigger 2326 prevents the dispensable substance in fluid volume 2310 from being under pressure by holding the spring 2314 and the piercer 2320 in place. When the device 2300 reaches the appropriate location in the GI tract, the enteric trigger 2326 degrades and/or dissolves (e.g., due to pH, change in pH, presence of certain enzyme, and/or concentration of certain enzyme) that the piercer retainer 2324 is no longer sufficient to hold back the pressure from the spring 2314. The spring 2314 forces the piercer 2320 into the gas cylinder 2316, puncturing the gas cylinder 2316 and causing gas at elevated pressure to leave the cylinder 2316. This causes the gas cylinder 2316 to press against the piston 2318 and apply pressure to the fluid volume 2310. The piston provides friction to cause the cap 2334 to open/deploy such that the dispensable substance is delivered out of the volume 2310. This results in delivery (e.g., topical delivery) of the therapeutic agent contained in the dispensable substance.

In some embodiments, the housing of the ingestible device 2300 has a diameter from about 8 mm to about 11 mm (e.g., from about 9.8 mm to about 10 mm), a length from about 23 mm to about 26.5 mm (e.g., from about 23.3 mm to about 26.3 mm), a wall thickness from about 0.4 mm to about 0.6 mm (e.g., about 0.5 mm), a fluid volume from about 230 μL to about 355 μL (e.g., from about 235 μL to about 349 μL), and/or a gas volume in the gas cylinder 2316 from about 150 μL to about 175 μL (e.g., about 160 μL).

FIG. 25 shows an embodiment of an ingestible device 2500, which contains a dispensable substance that is not under pressure when the subject swallows the ingestible device. The ingestible device 2500 has housing parts 2504 and 2506 connected by a union ring 2508 and with a fluid volume 2510 containing a dispensable substance, a spring 2514, a piston 2518, a spring retention pin 2536, and an O-ring 2532. A dispensable substance-containing cap 2538 seals in the dispensable substance (e.g., drug-containing liquid) after the housing part 2504 is filled with the dispensable substance (e.g., drug-containing liquid). A seal 2530 forms a gas seal between the spring retention pin 2536 and the housing part 2506. A spring retention cup 2522 retains the spring retention pin 2536. A pin retainer 2540 holds the spring retention pin 2536 in place with an enteric trigger 2526 that retains the pin retainer in place until it dissolves and used as the triggering mechanism. When the device 2500 is swallowed by the subject, the enteric trigger 2526 prevents the dispensable substance in fluid volume 2510 from being under pressure by holding the spring 2514 and the spring retention pin 2536 in place. When the device 2500 reaches the appropriate location in the GI tract, the enteric trigger 2526 degrades and/or dissolves (e.g., due to pH, change in pH, presence of certain enzyme, and/or concentration of certain enzyme) that the pin retainer 2540 is no longer sufficient to hold back the spring retention pin 2536, releasing spring 2514. The spring 2514 pushes against the piston 2518 such that the piston 2518 applies pressure to the fluid volume 2510. The piston provides friction to cause the cap 2534 to open/deploy such that the dispensable substance is delivered out of the volume 2510. This results in delivery (e.g., topical delivery) of the therapeutic agent out of the dispensable substance.

In some embodiments, the housing of the ingestible device 2500 has a diameter from about 8 mm to about 11 mm (e.g., from about 9.8 mm to about 10 mm), a length from about 23 mm to about 26.5 mm (e.g., from about 23.3 mm to about 26.1 mm), a wall thickness from about 0.4 mm to about 0.6 mm (e.g., about 0.5 mm), a fluid volume from about 395 μL to about 570 μL (e.g., from about 403 μL to about 559 μL).

FIGS. 26 and 27 show an ingestible device 2600 in its closed and open states, respectively. The ingestible device 2600 is configured similarly to ingestible device 2500 and having housing components 2604 and 2606 with a smaller profile than the housing component of ingestible device 2500. Fluid volume 2610 of ingestible device 2600 can have a smaller capacity than fluid volume 2510 of ingestible device 2500.

In some embodiments, the housing of the ingestible device 2600 has a diameter from about 8 mm to about 11 mm (e.g., from about 9.8 mm to about 10 mm), a length from about 23 mm to about 26.5 mm (e.g., from about 23.3 mm to about 26.1 mm), a wall thickness from about 0.4 mm to about 0.6 mm (e.g., about 0.5 mm), a fluid volume from about 395 μL to about 570 μL (e.g., from about 403 μL to about 559 μL).

FIG. 28 shows an embodiment of an ingestible device 2800, which contains a dispensable substance that is not under pressure when the subject swallows the ingestible device. The ingestible device 2800 has housing parts 2804 and 2806 connected by a union ring 2808 and with a fluid volume 2810 containing a dispensable substance, a spring 2814, a piston 2818, a spring retention pin 2836, and an O-ring 2832. A dispensable substance-containing cap 2838 seals in the dispensable substance (e.g., drug-containing liquid) after the housing part 2804 is filled with the dispensable substance (e.g., drug-containing liquid). A seal 2830 forms a gas seal between the spring retention pin 2836 and the housing 2806. A spring retention cup 2822 retains the spring retention pin 2836. A pin retainer 2840 holds the spring retention pin 2836 in place with an enteric trigger 2826 that retains the pin retainer in place until it dissolves and used as the triggering mechanism. When the device 2800 is swallowed by the subject, the enteric trigger 2826 prevents the dispensable substance in fluid volume 2810 from being under pressure by holding the spring 2814 and the spring retention pin 2836 in place. When the device 2800 reaches the appropriate location in the GI tract, the enteric trigger 2826 degrades and/or dissolves (e.g., due to pH, change in pH, presence of certain enzyme, and/or concentration of certain enzyme) that the pin retainer 2840 is no longer sufficient to hold back the spring retention pin 2836, releasing spring 2814. The spring 2814 pushes against the piston 2818 such that the piston 2818 applies pressure to the fluid volume 2810. The piston provides friction to cause the cap 2834 to open/deploy such that the dispensable substance is delivered out of the volume 2810. This results in delivery (e.g., topical delivery) of the therapeutic agent contained in the dispensable sub stance.

In some embodiments, the housing of the ingestible device 2800 has a diameter from about 10 mm to about 12 mm (e.g., from about 11.3 mm to about 11.5 mm), a length from about 23 mm to about 26.5 mm (e.g., from about 25.2 mm to about 26.2 mm), a wall thickness from about 0.4 mm to about 0.6 mm (e.g., about 0.5 mm), a fluid volume from about 790 μL to about 870 μL (e.g., from about 802 μL to about 855 μL).

FIG. 29A shows an outer view of the embodiment of ingestible device 2800, and FIG. 29B shows and an outer view of the housing component 2804 that retains a fluid volume 2810.

FIG. 30 shows the embodiment of the ingestible device 2800 in which the cap 2834 is opened/deployed.

FIG. 31 shows an embodiment of an ingestible device 3100, which contains a dispensable substance that is not under pressure when the subject swallows the ingestible device. The ingestible device 3100 has housing parts 3104 and 3106 and a fluid volume 3110 containing a dispensable substance, a piston 3118, a wave spring 3142, and an O-ring 3132. A dispensable substance-containing cap 3138 seals in the dispensable substance (e.g., drug-containing liquid) after the housing part 3104 is filled with the dispensable substance (e.g., the drug-containing liquid). A seal 3130 forms a gas seal between the switch 3146 and the housing 3106. A spring retention cup 3122 retains the wave spring 3142. A pin retainer 3140 holds the switch 3146 in place with an enteric trigger 3126 that retains the pin retainer in place until it dissolves and is used as the triggering mechanism. When the device 3100 is swallowed by the subject, the enteric trigger 3126 prevents the dispensable substance in fluid volume 3110 from being under pressure by holding the wave spring 3142 and the switch 3146 in place. When the device 3100 reaches the appropriate location in the GI tract, the enteric trigger 3126 degrades and/or dissolves (e.g., due to pH, change in pH, presence of certain enzyme, and/or concentration of certain enzyme) that the pin retainer 3140 is no longer sufficient to hold back the wave spring 3142 and releasing switch 3146. The switch 3146 completes a circuit with the gas cell 3144, which begins gas production. As pressure builds, piston 3118 slides along a trace and closes the circuit via a conductive O-ring 3132. The circuit opens when the trace ends at a defined travel distance to halt gas production by the gas cell 3144. The piston 3118 applies pressure to the fluid volume 3110 and provides friction to cause the cap 3134 to open/deploy such that the dispensable substance is delivered out of the volume 3110. This results in delivery (e.g., topical delivery) of the therapeutic agent contained in the dispensable substance.

In some embodiments, the housing of the ingestible device 3100 has a diameter from about 10 mm to about 12 mm (e.g., from about 11 mm to about 11.5 mm), a length from about 23 mm to about 26.5 mm (e.g., from about 25.2 mm to about 26.2 mm), a wall thickness from about 0.4 mm to about 0.6 mm (e.g., about 0.5 mm), a fluid volume from about 880 μL to about 940 μL (e.g., from about 890 μL to about 930 μL).

FIG. 32A shows an outer view of the embodiment of ingestible device 3100, and FIG. 32B shows an outer view of the housing component 3104 that retains a fluid volume 3110.

FIG. 33 shows another view of the embodiment of the ingestible device 3100.

FIG. 34 shows the embodiment of the ingestible device 3100 in which the cap 3134 is opened/deployed.

In some embodiments, a length of an ingestible device can be reduced to achieve a modified 00 standardized length, e.g., approximately 23.3 mm in length, while maintaining a same diameter as a standard size 000. A reduced length of the ingestible device may result in a reduced volume available for the dispensable substance. Adjusting one or more dimensions of a gas cylinder within the ingestible device and/or altering a position of a piston may be utilized to increase an available volume for the dispensable substance, while maintaining a threshold dispensable substance volume and/or pressure provided by the gas cylinder for the ingestible device. Example embodiments are described with reference to FIGS. 35-40 herein.

FIG. 35 shows an embodiment of an ingestible device 3500 for epithelial delivery in which a length of the ingestible device is reduced to achieve a modified size 00 submucosal device, and which contains a dispensable substance that is not under pressure when the subject swallows the ingestible device. The ingestible device 3500 has housing parts 3504 and 3506 connected by a union ring 3508 and with a fluid volume 3510 containing a dispensable substance, a spring 3514, a gas cylinder 3516, a piston 3518, a piercer 3520, and an O-ring 3532. Gas cylinder 3516 is retained by retention element 3528. A seal 3530 forms a gas seal between the piercer 3520 and the housing 3506. A spring retention cup 3522 retains the spring-loaded piercer 3520. A piercer retainer 3524 holds the piercer 3520 in place with an enteric trigger 3526 that retains the piercer retainer in place until it dissolves and used as the triggering mechanism. When the device 3500 is swallowed by the subject, the enteric trigger 3526 prevents the dispensable substance in fluid volume 3510 from being under pressure by holding the spring 3514 and the piercer 3520 in place. When the device 3500 reaches the appropriate location in the GI tract, the enteric trigger 3526 degrades and/or dissolves (e.g., due to pH, change in pH, presence of certain enzyme, and/or concentration of certain enzyme) that the piercer retainer 3524 is no longer sufficient to hold back the pressure from the spring 3514. The spring 3514 forces the piercer 3520 into the gas cylinder 3516, puncturing the gas cylinder 3516 and causing gas at elevated pressure to 3534 leave the cylinder 3516. This causes the gas cylinder 3516 to press against the piston 3518 and apply pressure to the fluid volume 3510. The piston provides friction to cause the cap 3534 to open/deploy such that the dispensable substance is delivered out of the volume 3510. This results in epithelial delivery of the therapeutic agent contained in the dispensable substance.

In some embodiments, the ingestible device 3500 can retain a dispensable substance volume from about 250 μL to about 350 μL (e.g., about 267 μL), can have an expansion volume from about 230 μL to about 260 μL (e.g., about 243 μL), and can have a gas cylinder fill volume from about 140 μL to about 150 μL (e.g., about 160 μL).

In some embodiments, one or more adjustments to a piston length and/or gas cylinder dimensions can be modified for the ingestible device, e.g., ingestible device 3500. FIGS. 36-40 depict various modifications to piston length and/or gas cylinder dimensions of the ingestible device structure described with reference to FIG. 35 .

FIG. 36 shows an embodiment of an ingestible device 3600 in which a length of the ingestible device is reduced to achieve a modified size 00 submucosal device and a piston length is reduced. As depicted in FIG. 36 , ingestible device 3600 includes a piston 3618, a gas cylinder 3616, and a fluid volume 3610.

In some embodiments, a 280 PSIG fill pressure of the gas cylinder corresponds to a drive pressure volume from about 70-80 μL (e.g., about 75 μL). In some embodiments, a 240 PSIG fill pressure of the gas cylinder corresponds to a drive pressure volume from about 90-100 μL (e.g., about 95 μL).

FIG. 37 shows an embodiment of an ingestible device 3700 in which a length of the ingestible device is reduced to achieve a modified size 00 submucosal device and a piston length is reduced. As depicted in FIG. 37 , ingestible device 3700 includes a piston 3718, a gas cylinder 3716, and a fluid volume 3710. In some embodiments, the ingestible device 3700 can retain a dispensable substance volume from 300 μL to about 350 μL, (e.g., about 332 μL), can have an expansion volume from about 320 μL to about 380 μL, (e.g., about 336 μL), and can have a gas cylinder fill volume from about 65 μL to about 85 μL (e.g., about 75 μL). In some embodiments, a 280 PSIG fill pressure of the gas cylinder corresponds to a drive pressure volume from about 140-150 μL (e.g., about 145 μL). In some embodiments, a 240 PSIG fill pressure of the gas cylinder corresponds to a drive pressure volume from about 170-190 μL (e.g., about 180 μL).

FIG. 38 shows an embodiment of an ingestible device 3800 in which a length of the ingestible device is reduced to achieve a modified size 00 submucosal device and a piston length is reduced. As depicted in FIG. 38 , ingestible device 3800 includes a piston 3818, a gas cylinder 3816, and a fluid volume 3810. In some embodiments, the ingestible device 3800 can retain a dispensable substance volume from 300 μL to about 350 μL, (e.g., about 335 μL), can have an expansion volume from about 300 μL to about 320 μL (e.g., about 306 μL), and can have a gas cylinder fill volume from about 35 μL to about 45 μL (e.g., about 40 μL). Piston shape of piston 3818 may result in residual dispensable substance volume of about 80 μL (of a total of 335 μL delivered) within the dispensable substance housing after delivery.

FIG. 39 shows an embodiment of an ingestible device 3900 in which a length of the ingestible device is reduced to achieve a modified size 00 submucosal device and a gas cylinder diameter is modified. As depicted in FIG. 39 , ingestible device 3900 includes a piston 3918, a gas cylinder 3916, and a fluid volume 3910. In some embodiments, the ingestible device 3900 can retain a dispensable substance volume from 300 μL to about 350 μL (e.g., about 335 μL), can have an expansion volume from about 250 μL to about 290 μL (e.g., about 271 μL), and can have a gas cylinder fill volume from about 70 μL to about 80 μL (e.g., about 75 μL). Piston shape of piston 19166 may result in residual dispensable substance volume from about 70-90 μL (e.g., about 80 μL) of a total amount of dispensable substance volume delivered within the housing after delivery.

FIG. 40 shows an embodiment of an ingestible device 4000 in which a length of the ingestible device is reduced to achieve a modified size 00 submucosal device and a gas cylinder diameter is modified. As depicted in FIG. 40 , ingestible device 4000 includes a piston 4018, a gas cylinder 4016, and a fluid volume 4010. In some embodiments, the ingestible device 4000 can retain a dispensable substance volume from 300 μL to about 350 μL (e.g., about 332 μL), can have an expansion volume from about 220 μL to about 270 μL (e.g., about 240 μL), and can have a gas cylinder fill volume from about 125 μL to about 145 μL (e.g., about 138 μL). In some embodiments, a 240 PSIG drive pressure of the gas cylinder corresponds to a fill pressure from about 780-800 PSIG (e.g., 792.7 PSIG). In some embodiments, 280 PSIG fill pressure of the gas cylinder corresponds to a drive pressure from about 910-930 PSIG (e.g., about 925 PSIG). In some embodiments, a 320 PSIG drive pressure of the gas cylinder corresponds to a fill pressure from about 1040-1060 PSIG (e.g., 1057 PSIG).

In some embodiments, a puncture force required to puncture a gas cylinder can be reduced such that a shorter/lower force spring can be utilized and/or a shorter/stiffer spring can be utilized.

In some embodiments, as depicted in FIGS. 41A-41C, a nozzle opening 4102 can be covered by a covering including a member, e.g., a patch 4104, that forms a barrier between a dispensable substance 4112 retained within the housing 4110 and an environment external to the ingestible device. A patch 4104 can be formed of a materials that is a degradable material, an erodible material and a dissolvable material. A patch can be a barrier film composed of various materials, for example, polyethylene (PE), polypropylene, cyclic olefin copolymer (COC), cyclo-olefin-polymer (COP), polycarbonate, polyvinyl chloride (PVC), polyurethane, or the like. A patch may be a mutli-layer film, e.g., two or more layers of a same or different material, for enhanced barrier properties. Multi-layer construction of a patch 4104 can include, for example, PE/ethylene-vinyl alcohol copolymer (EVOH), ethylene-vinyl acetate (EVA)/EVOH/EVA, EVA/polyvinylidene chloride (PVDC)/EV, or the like. In some embodiments, multi-layer construction of a patch can include a metal layer.

A patch 4104 can have various shape profiles, for example, circular, rectangular, polygonal, or asymmetric profile. In some embodiments, as depicted in FIG. 41 , a patch may be affixed off-center 4106 over the nozzle opening 4102 on an outside surface of the ingestible device such that a force of a jet expelled through the nozzle opening 4102, e.g., by pressurized release of the dispensable substance, may preferentially move the patch away from a direction of the formed jet.

A patch 4104 may be affixed loosely over a nozzle opening, e.g., using adhesive or another pressure sensitive method, or using static attraction. Adhesive to affix the patch may be utilized on a surface surrounding the nozzle but not directly on the nozzle.

In some embodiments, a film, a coating, a foil, a band, or the like may be placed over the patch that is affixed over the nozzle opening, and may be composed on a dissolvable material, e.g., enteric material, such that the film, coating, foil, or band holds the patch in place over the nozzle opening during handling, storage, and ingestion of the ingestible device. In one example, a band 4108 is composed of a material that can dissolve upon entry into a body. The film or band may be composed of a material that is water soluble, e.g., hydroxypropyl methyl cellulose (HPMC), hydroxypropylmethylcellulose acetate succinate (HPMCAS), or gelatin. The film or band 4108 may be composed of a material that includes a pH-dependent solubility, e.g., composed of or including polymethacrylate, such that the material is more stable under acidic conditions, e.g., pH 1-4, and where a rate of dissolution increases when the material is exposed to higher pH, e.g., pH 5-7.

In some embodiments, a band covering a nozzle opening can be composed of a heat shrink material that is heat shrunk to the housing such that it provides a nozzle covering. An example of a heat shrink material is polyethylene terephthalate (PET). Additional examples of heat shrink materials include polyolefin, polyethylene, LDPE, PTFE, FEP and COC. In general, such a heat shrink material does not operate by being dissolved. Instead, it is broken (e.g., punctured) by the pressure of the dispensable material applied to the heat shrink material. Such a heat shrunk band can have a thickness of, for example, from about 5 μm to about 100 μm (e.g., from about 5 μm to about 50 μm, about 10 μm, about 12 μm, about 15 μm, about 50 μm). Specific examples include heat shrunk PET (e.g., medical film) having a thickness of about 12 μm, heat shrunk polylefin (e.g., transit packing film) having a thickness of about 15 μm, and heat shrunk polyethylene (e.g., transit packing film) having a thickness of about 50 μm.

In general, a covering (e.g., a film, a coating, a foil, a band) of a nozzle opening can be scored, e.g., to make it easier for the seal to be broken when desired. Generally, such scoring can be configured as desired. As an example, scoring can be configured as a series of parallel lines. As another example, scoring can be configured as a grid (cross-hatched). As a further example, scoring can be configured as a plurality of dots (e.g., equally spaced dots). In some embodiments of a scored seal, the seal is composed of LDPE, for example of having a thickness of from 20 μm to 75 μm (e.g., 25 μm, 50 μm). For example, a seal composed of LDPE can be scored with stripes or a grid or a plurality of dots, with the LDPE having a thickness of 25 μm or 50 μm.

In some embodiments, covering (e.g., a coating, a film, a band, or a patch has a minimal burst pressure. In some embodiments, for example, the minimal burst pressure is less than 420 psig, 410 psig, 400 psig, 390 psig, 380 psig, 370 psig, 360 psig, 350 psig, 340 psig, 330 psig, 320 psig, 310 psig, 300 psig, 290 psig, 280 psig, 270 psig, 260 psig, 250 psig, 240 psig, 230 psig, 220 psig, 210 psig, 200 psig, 190 psig, 180 psig, 170 psig, 160 psig, 150 psig, 140 psig, 130 psig, 120 psig, 110 psig, 100 psig, 90 psig, 80 psig, 70 psig, 60 psig, 50 psig, 40 psig, 30 psig, or 20 psig. Generally, the minimal burst pressure is more than 5 psig (e.g., more than 10 psig, more than 25 psig, more than 50 psig more than 80 psig). For example, in certain embodiments, the burst pressure can be in a range of from 5 psig to any one of the minimal burst pressures noted earlier in this paragraph.

In some embodiments, a coating or film can be applied over a nozzle opening 4102 that may dissolve/degrade or otherwise become unstable after the ingestion of the ingestible device. In some embodiments, the coating or film is hydrophobic. The coating or film can be structurally weakened by drilling/scoring, e.g., using laser drilling, and/or can be composed of a material that weakens based on an environment surrounding the material, e.g., an enteric material within the body. In one example, laser microtoming can be utilized to thin a coating or film, e.g., a sanding/polishing process, to reduce the coating or film thickness. In some embodiments, a coating or film of an enteric material can be applied over a nozzle opening 4102 and a portion of an outer surface of the ingestible device. A machining/polishing processes can be utilized to control a final thickness of the applied coating or film, e.g., centerless lapping or grinding. The coating or film can be further processed using a laser to drill, score, and/or perforate a portion of the coating or film to mechanically weaken the coating or film.

FIGS. 42A-47C depict embodiments of a patch, coating, film, foil and/or band that can be affixed to or in contact with the nozzle opening. While such embodiments are depicted in these figures, the disclosure is not limited in this sense. In some embodiments, a combination of more than one (e.g., more than two, more than three) such approaches to covering a nozzle opening may be used in a given ingestible device. Further, variations on the approaches disclosed herein are available so long as they generally comport with the relevant function(s), such as, for example, providing a barrier between a dispensable substance (e.g., drug-containing liquid) retained within the drug housing and an environment external to the ingestible device.

In some embodiments, as depicted in FIGS. 42A and 42B, a nozzle opening 4202 can be covered by a covering including a member 4248, e.g., a patch, film, foil, band, or the like, that forms a barrier between a fluid volume 4210 including a dispensable substance (e.g., drug-containing liquid) retained within the housing and an environment external to the ingestible device. Certain embodiments including a nozzle covering member 4202 formed of a film, foil, patch, band, or the like are discussed, for example, with reference to FIGS. 17, 18, 19A-N of U.S. Ser. No. 62/932,459, and optionally applicable to FIGS. 42A and 42B.

Internal pressure from a pressurized dispensable substance, e.g., during pressurized dispensable substance release, can cause the dispensable substance to puncture the covering member or partially peel/detach the covering member from the outer surface of the ingestible device to allow dispensable substance-containing jets 4262 to form. The covering member 4248 can be composed of various materials, e.g., PE, PP, PVC, cellulose acetate, hot blocking film, and the like. In some embodiments, the covering member can be composed of material that is intended to be insoluble in gastric media but may break down in the small intestine based on pH (e.g., enteric materials) or one or more enzymes, such as, for example, one or more pancreatic enzymes (e.g., lipid-based materials). The covering member 4248 can be composed of material that can hydrate and/or soften when exposed to gastric media without substantially dissolving. The covering member 4248 in this embodiment and others described herein can be composed on a gas-permeable membrane, e.g., which may help with de-gassing during a process of filing the ingestible device. The covering member can be applied, for example, in a post-molding operation, e.g., from a reel.

In some embodiments, the covering member 4248 can be a thin shrink-fit film or adhesive label component applied to an external surface of the ingestible device to cover the nozzle openings. In certain embodiments, the thin film or adhesive label can be a thin barrier, e.g., having a thickness from 20 μm to 40 μm (e.g., from 25 μm to 35 μm, 30 μm).

In some embodiments, the covering member 4248 can be an external band that is applied to cover the nozzle openings 4202. In certain embodiments, the band can be, for example, from 100 μm to 200 μm (e.g., from 125 μm to 175 μm, e.g., 150 μm) thick. Optionally, the band can be composed of materials such as gelatin, HPMC, or other materials that are soluble in gastric media, or can be composed of enteric material.

In some embodiments, the covering member 4248 can be a partial film or covering, e.g., an external cap, that is applied to an outside of the ingestible device to cover the nozzle openings 4202. The cap can be, for example, from 100 μm to 200 μm (e.g., from 125 μm to 175 μm, e.g., 150 μm) thick and/or cover less than the full exterior of the ingestible device.

In some embodiments, as depicted in FIGS. 43A and 43B, a covering member 4348, e.g., patch, film, foil, band, coating, or the like, that forms a barrier between a fluid volume 4310 including a dispensable substance (e.g., a drug-containing liquid) retained within the housing 4304 and an environment external to the ingestible device can be applied and/or affixed to an interior surface 4364 of the ingestible device. In some embodiments, the covering member 4348 is a thin film that is applied to an internal surface of a primary container 4304 of the ingestible device, e.g., during a molding process, to cover the nozzle openings 4302. Internal pressure from a pressurized dispensable substance, e.g., during pressurized dispensable substance release, can cause the dispensable substance to puncture the covering member or partially peel/detach the covering member from the outer surface of the ingestible device to allow dispensable substance-containing jets 4362 to form. The covering member 4348 can be composed of various materials, e.g., COC-based films such as COC+LLDPE laminate, and the like. In some embodiments, the covering member 4348 can be composed of material that is intended to be insoluble in gastric media but may break down in the small intestine based on pH (e.g., enteric materials) and/or or one or more enzymes, such as, for example, one or more pancreatic enzymes (e.g., lipid-based materials). The covering member 4348 can be composed of material that can hydrate and/or soften when exposed to gastric media without substantially dissolving. The covering member 4348 in this embodiment and others described herein can be composed on a gas-permeable membrane, e.g., which may help with de-gassing during a process of filing the ingestible device. The covering member 4348 can be applied, for example, using a molding process, e.g., based on an in-molded label or blow molded onto an interior surface 4364 of the ingestible device. The covering member can be, for example, from 20 μm to 40 μm (e.g., from 25 μm to 35 μm, 30 μm) thick. In some embodiments, the covering member can be applied/affixed without an adhesive, e.g., molded bond.

In some embodiments, as depicted in FIGS. 44A and 44B, a covering member can be a feature, such as, for example, a molded feature 4466 formed on (or adjacent to) an interior end of a nozzle opening 4402 and which forms a barrier between a fluid volume 4410 including a dispensable substance (e.g., drug-containing liquid) retained within the housing 4404 and an environment external to the ingestible device. Internal pressure from a pressurized dispensable substance, e.g., during pressurized dispensable substance release, can cause the dispensable substance to puncture the covering member 4466 fully or partially peel/detach the covering member from the outer surface of the ingestible device to allow dispensable substance-containing jets 4464 to form. The covering member can be composed of various materials, e.g., COC-based films such as COC+LLDPE laminate, and the like. In some embodiments, the covering member 4466 can be composed of material that is intended to be insoluble in gastric media but may break down in the small intestine based on pH (e.g., enteric materials) and/or one or more enzymes, such as, for example, one or more pancreatic enzymes (e.g., lipid-based materials). The covering member 4466 can be composed of material that can hydrate and/or soften when exposed to gastric media without substantially dissolving.

In some embodiments, as depicted in FIGS. 45A and 45B, a covering member 4548 can be a covering member that is tethered 4568 to the ingestible device, e.g., tethered to an outer portion of the housing 4504. The covering member 4548 can be formed of a flexible material, e.g., an elastomer material. Internal pressure from a pressurized dispensable substance, e.g., during pressurized dispensable substance release, can cause the dispensable substance to detach/displace a portion or all of the covering member from the nozzle opening 4502 of the ingestible device to allow dispensable substance-containing jets 4562 to form.

In some embodiments, as depicted in FIGS. 46A and 46B, a covering member can be a plug 4650, e.g., an elastomer plug, that can block the nozzle opening 4602 from an outside surface of the ingestible device. The plug can be tethered to a housing component 4604 of the ingestible device to prevent dispersion of the released plug into the body. The plug 4650 can be formed of biodegradable materials such that the plug can be processed by the body. Internal pressure from a pressurized dispensable substance, e.g., during pressurized dispensable substance release, can cause the dispensable substance to detach/displace the plug 4650 from the nozzle opening of the ingestible device to allow dispensable substance-containing jets 4662 to form.

In some embodiments, as depicted in FIGS. 47A-47C, a nozzle opening 4702 can be blocked by a plug 4750 that is formed by applying a liquid-fil gel from an outside apparatus 4770 of the ingestible device, e.g., via a nozzle or rotating mandrel. The liquid-fill gel can harden before a dispensable substance filling process to provide a plug 4750. The gel can be composed of a material that is substantially insoluble in gastric media/dispensable substance, but can break down in small intestine-based pH (e.g., an enteric material) and/or one or more enzymes, such as for example, one or more pancreatic enzymes (e.g., lipid-based material). Internal pressure from a pressurized dispensable substance, e.g., during pressurized dispensable substance release, can cause the dispensable substance to displace the gel from the nozzle opening 4702 of the ingestible device to allow dispensable substance-containing jets 4762 to form.

FIGS. 48 and 49 depict an embodiment of an ingestible device 4800 utilizing an internal piston. Ingestible device 4800 contains a dispensable substance that is not under pressure when the subject swallows the ingestible device. In FIG. 48 , the nozzles 4802 are depicted as covered, and in FIG. 49 the nozzles 4802 are uncovered. The ingestible device 4800 has housing parts 4804 and 4806 connected by a union ring 4808 and with a fluid volume 4810 containing a dispensable substance, a spring 4814, a gas cylinder 4816, a first piston 4818 a and a second piston 4818 b, a piercer 4820, and an O-ring 4832. The piercer 4820 is held in place with an enteric trigger 4826 that dissolves and used as the triggering mechanism. When the device 4800 is swallowed by the subject, the enteric trigger 4826 prevents the dispensable substance in fluid volume 4810 from being under pressure by holding the spring 4814 and the piercer 4820 in place. When the device 4800 reaches the appropriate location in the GI tract, the enteric trigger 4826 degrades and/or dissolves (e.g., due to pH, change in pH, presence of certain enzyme, and/or concentration of certain enzyme) such that the spring 4814 forces the piercer 4820 into the gas cylinder 4816, puncturing the gas cylinder 4816 and causing gas at elevated pressure to leave the cylinder 4816. This causes the gas cylinder 4816 to press against the first piston 4818 a and apply pressure to the fluid volume 4810. The pressurized fluid volume 4810 applies pressure to the second piston 4818 b cause the second piston 4818 b to slide and expose the nozzles 4802 such that the dispensable substance is delivered out of the nozzles 4802 in the form of a jet. This can result in trans-epithelial and/or epithelial delivery of the therapeutic agent contained in the dispensable substance.

In some embodiments, a plug/cover can be affixed over a nozzle opening, where the plug/cover is further connected to a piercer component of the ingestible device via connectors and a ring component. FIGS. 50A and 50B depict an embodiment of an ingestible device 5000 including a plug/cover assembly. Ingestible device 5000 includes nozzle opening(s) 5002, a drug container 5004, a drive housing 5006, an o-ring 5032, a retention element 5028, a piercer 5020, a gas seal 5030, a trigger element 5026, a trigger support 5024, a spring 5014, a gas cylinder 5016, a union ring 5008, and a piston 5018. The ingestible device 5000 optionally includes a nozzle cover 5048.

A plug/cover assembly can be a single formed piece, e.g., composed of a plastic material, and fitted externally to the ingestible device such that the plug(s) 5050 cover the nozzle opening(s) 5002 on the ingestible device 5000. The plug/cover assembly can further include connectors 5052 that connect the plug/cover assembly to a ring 5054 component that can be attached to a top of the piercer 5020 and external to a trigger element 5026, such that the ring component 5054 is pulled down by the piercer 5020 when the piercer is released, e.g., after the trigger element 5026 dissolves/degrades, and the plug/cover 5050 are pulled away from the nozzle opening 5002 by the movement of the ring 5054. In some embodiments, the plug/cover 5050 are pulled away from the nozzle opening 5002 by the movement of the ring 5054 in a direction parallel to a length of the ingestible device 5000, e.g., along the outer surface of the ingestible device. In some embodiments, the plug/cover 5050 are pulled away from the nozzle opening 5002 by the movement of the ring 5054 in a direction outwards, e.g., normal, or angled-away, from an outer surface of the ingestible device 5000.

In some embodiments, a band can be affixed over one or more nozzle openings, where the band is further connected to a piercer component of the ingestible device via connectors and a ring component. FIGS. 51A and 51B depicts an embodiment of an ingestible device 5100 including a band assembly. Ingestible device 5100 includes nozzle opening(s) 5102, a drug container 5104, a drive housing 5106, an o-ring 5132, a retention element 5128, a piercer 5120, a gas seal 5130, a trigger element 5126, a trigger support 5124, a spring 5114, a gas cylinder 5116, a union ring 5108, and a piston 5118. The ingestible device 5100 optionally includes a nozzle cover 5148.

A band assembly can be a single formed piece, e.g., composed of a plastic material, including a band 5156, connectors 5152, and a ring component 5154. A band assembly can be instead multi-piece assembly composed of a band 5156 that is placed around the ingestible device 5100 during a filling process and a connector/ring assembly that are affixed to the band 5156 and piercer component 5120. The band assembly can be connected to the piercer 5120 by a ring component 5154 that can be attached to a top of the piercer component and external to a trigger element 5126, such that the ring component 5154 is pulled down by the piercer 5120 when the piercer is released, e.g., after the trigger element 5126 dissolves/degrades, and the band 5156 is pulled away from the nozzle opening(s) 5102, e.g., along a length of the ingestible device 5100, to expose the nozzle opening(s) 5102 by the movement of the ring 5154 prior or simultaneously to the delivery of the dispensable substance via the nozzle openings 5102.

In some embodiments, as depicted in FIGS. 52A-52D, an ingestible device 5200 includes a sliding cover 5248. The sliding cover 5248 can be a single formed piece, e.g., a sleeve composed of a plastic material, and fitted externally to the ingestible device 5200 such that a portion of the sliding cover covers the nozzle opening(s) 5202 on the ingestible device 5200. The sliding cover 5248 can be attached to a top of the piercer component 5220 and external to a trigger element 5226, such that the sliding cover 5248 is pulled down by the piercer 5220 when the piercer is released, e.g., after the trigger element 5226 dissolves/degrades, and the sliding cover 5248 is pulled away from the nozzle opening 5202 by the movement of the piercer 5220. The sliding cover 5248 can be pulled away from the nozzle openings 5202 by the movement of the sliding cover in a direction parallel to a length of the ingestible device 5200, e.g., along the outer surface of the ingestible device, prior or simultaneously to the delivery of the dispensable substance within fluid volume 5210 via the nozzle openings 5202.

In some embodiments, as depicted in a partial rendering of an ingestible device 5300 in FIGS. 53A and 53B, ingestible device 5300 includes a cap 5334 affixed over one end of an ingestible device 5300 and partially enclosing a volume 5310. A seal 5358, e.g., an over-molded elastomer based seal, can be utilized to seal a dispensable substance within the volume 5310 and prevent the dispensing of the dispensable substance while the cap 5334 is affixed over the end of the ingestible device 5300. The seal 5358 can additionally prevent movement of the cap 5334 prior to a delivery of the dispensable substance. When the device 5300 is swallowed by the subject, the enteric trigger prevents the dispensable substance in the fluid volume from being under pressure by holding the spring and the piercer in place. When the device reaches the appropriate location in the GI tract, the enteric trigger degrades and/or dissolves (e.g., due to pH, change in pH, presence of certain enzyme, and/or concentration of certain enzyme) such that the spring forces the piercer into the gas cylinder, puncturing the gas cylinder and causing gas at elevated pressure to leave the cylinder. This causes the gas cylinder to press against the piston and apply pressure to the fluid volume. The pressurized fluid volume applies pressure to the cap and causes the cap to slide open and expose the nozzles such that the dispensable substance is delivered out of the nozzles in the form of a jet. This can result in trans-epithelial and/or epithelial delivery of the therapeutic agent contained in the dispensable substance.

In some embodiments, as depicted in a partial rendering of an ingestible device in FIGS. 54A and 54B, an ingestible device 5400 includes an inflated membrane volume 5460, e.g., a gas balloon or similar, located within the volume 5410 including a dispensable substance and arranged to seal the nozzle openings 5402 while the inflated volume 5460 is inflated. In some embodiments, the inflated membrane volume 5460 may conform to one or more contours, e.g., an inner curvature, of the ingestible device housing 5404. The inflated membrane volume 5460 can be composed of a balloon and/or soft material, e.g., a low durometer elastomer. When the device 5400 is swallowed by the subject, the enteric trigger prevents the dispensable substance in the fluid volume from being under pressure by holding the spring and the piercer in place. When the device reaches the appropriate location in the GI tract, the enteric trigger degrades and/or dissolves (e.g., due to pH, change in pH, presence of certain enzyme, and/or concentration of certain enzyme) such that the spring forces the piercer into the gas cylinder, puncturing the gas cylinder and causing gas at elevated pressure to leave the cylinder. This causes the gas cylinder to press against the piston and apply pressure to the fluid volume. The pressurized fluid volume applies pressure to the inflated membrane volume 5460 and causes the inflated membrane volume to deflate or otherwise reposition to expose the nozzles openings 5402 such that the dispensable substance is delivered out of the nozzles in the form of a jet. This can result in trans-epithelial and/or epithelial delivery of the therapeutic agent contained in the dispensable substance.

In some embodiments, as depicted in a partial rendering of an ingestible device in FIG. 55 , the ingestible device 5500 does not include a covering member. For example, the nozzle openings 5502 may be exposed such that when the ingestible device 5500 is swallowed/inserted, an air gap in the nozzle openings 5502 and/or surface tension effects may prevent or deter gastric media from damaging the internal components or dispensable substance (e.g., drug-containing liquid) within the ingestible device. In other words, a differential force may be generated by the movement of the ingestible device within the gastric region between external intestinal forces/pressure and internal forces of the dispensable substance within the volume of the ingestible device. For example, a surface tension of the dispensable substance within a volume 5510 of the ingestible device can be higher than a surrounding environment, e.g., external intestinal forces/pressure within a gastric region in the body, such that a substantial percentage of the dispensable substance is retained within the volume of the ingestible device until a point of delivery of the dispensable substance, e.g., until piston 5518 applies pressure to the volume 5510 to force the dispensable substance retained within the volume 5510 out of the nozzle opening(s) 5502. In one example, at least 75% of the dispensable substance (e.g., at least 85%, at least 95% of the dispensable substance) is retained within the volume of the ingestible device until a point of delivery of the dispensable substance within a gastric region in the body.

Delivery of Therapeutics

Provided herein are ingestible devices and methods that deliver therapeutic agents into the intestinal lumen, mucus, mucosa and/or submucosa by topical, epithelial or trans-epithelial administration to the GI tract of a subject. Current methods of administration for most large molecule therapeutic agents or small molecule therapeutic agents with poor oral bioavailability are subcutaneous (SC), intramuscular (IM), or bolus intravenous (IV) injection targeting the systemic circulation. The devices and methods described herein provide an alternative route of administration to current injectable medications, which can lead to greater convenience and compliance since they minimize or avoid the logistical challenges, patient compliance and adherence challenges, pain, and discomfort associated with traditional routes of administration.

In some embodiments of the devices or methods described herein, the therapeutic is released at a location in the small intestine of the subject. In some embodiments of any of the devices or methods described herein, the location is in the proximal portion of the small intestine (e.g., duodenum or jejunum). In some embodiments of any of the devices or methods described herein, the location is in the distal portion of the small intestine (e.g., jejunum or ileum). In some embodiments of the devices or methods described herein, the therapeutic is released at a location in the large intestine of the subject. In some embodiments of any of the devices or methods described herein, the location is in the proximal portion of the large intestine (e.g., cecum, ascending colon, or transverse colon). In some embodiments of any of the devices or methods described herein, the location is in the distal portion of the large intestine (e.g., transverse colon or descending colon).

Also, by providing a higher concentration of therapeutic in GI tissue, the devices and methods described herein are particularly well-suited for treatment of diseases and conditions of the endoderm, including the liver.

In some embodiments of any of the devices or methods described herein, the releasing of the therapeutic is triggered by one or more of: a pH in the jejunum of about 6.1 to about 7.2, a pH in the mid small bowel of about 7.0 to about 7.8, a pH in the ileum of about 7.0 to about 8.0, a pH in the right colon of about 5.7 to about 7.0, a pH in the mid colon of about 5.7 to about 7.4, or a pH in the left colon of about 6.3 to about 7.7, such as about 7.0.

In some embodiments of any of the devices or methods described herein, the releasing of the therapeutic is triggered by degradation of a release component located in the device. In some embodiments of any of the devices or methods described herein, the releasing of the therapeutic is dependent on enzymatic activity at or in the vicinity of the location. In some embodiments of any of the devices or methods described herein, the composition includes a plurality of electrodes including a coating, and releasing the therapeutic is triggered by an electric signal by the electrodes resulting from the interaction of the coating with an intended site of release of the therapeutic. In some embodiments of any of the devices or methods described herein, the release of the therapeutic is triggered by a remote electromagnetic signal. In some embodiments of any of the devices or methods described herein, the release of the therapeutic is triggered by generation in the composition of a gas in an amount sufficient to expel the therapeutic. In some embodiments of any of the devices or methods described herein, the release of the therapeutic is triggered by an electromagnetic signal generated within the device according to a pre-determined drug release profile.

Therapeutics for Delivery

TNFα Inhibitors

In some embodiments, the therapeutic suitable for use with the devices and methods described herein is a TNFα inhibitor. The terms “TNFα inhibitor” or “TNF-alpha inhibitor” refer to an agent which directly or indirectly inhibits, impairs, reduces, down-regulates, or blocks TNFα activity and/or expression. In some embodiments, a TNFα inhibitor is an inhibitory nucleic acid, an antibody or an antigen-binding fragment thereof, a fusion protein, a soluble TNFα receptor (a soluble TNFR1 or a soluble TNFR2), or a small molecule TNFα antagonist. In some embodiments, the inhibitory nucleic acid is a ribozyme, small hairpin RNA, a small interfering RNA, an antisense nucleic acid, or an aptamer.

In other examples, such indirect TNFα inhibitors can be a small molecule inhibitor of a signaling component downstream of a TNFα receptor (e.g., any of the signaling components downstream of a TNFα receptor described herein or known in the art), a small molecule inhibitor of a protein encoded by a TNFα-induced gene (e.g., any protein encoded by a TNFα-induced gene known in the art), and a small molecule inhibitor of a transcription factor selected from the group of NF-κB, c-Jun, and ATF2.

Inhibitory Nucleic Acids of TNFα

Exemplary TNFα inhibitors that are inhibitory nucleic acids targeting TNFα include, e.g., antisense DNA (e.g., Myers et al., J Pharmacol Exp Ther. 304(1):411-424, 2003; Wasmuth et al., Invest.

Ther. 17(10): 1743-1753, 2009; Ogawa et al., PLoS One 9(3): e92073, 2014; Ding et al., Bone Joint 94-6(Suppl. 11):44, 2014; and Hernandez-Alejandro et al., J. Surgical Res. 176(2):614-620, 2012), and microRNAs (see, e.g., WO 15/26249). In some embodiments, the inhibitory nucleic acid blocks pre-mRNA splicing of TNFα (e.g., Chiu et al., Mol. Pharmacol. 71(6): 1640-1645, 2007).

In some embodiments, the inhibitory nucleic acid, e.g., an aptamer (e.g., Orava et al., ACS Chem Biol. 2013; 8(1): 170-178, 2013), can block the binding of a TNFα protein with its receptor (TNFR1 and/or TNFR2).

In some embodiments, the inhibitory nucleic acid can down-regulate the expression of a TNFα-induced downstream mediator (e.g., TRADD, TRAF2, MEKK1/4, MEKK4/7, JNK, AP-1, ASK1, RIP, MEKK 3/6, MAPK, NIK, IKK, NF-κB, p38, JNK, IκB-α, or CCL2). Further teachings of downstream TNFα-induced mediators can be found in, e.g., Schwamborn et al., BMC Genomics 4:46, 2003; and Zhou et al., Oncogene 22: 2034-2044, 2003, incorporated by reference herein. Additional aspects of inhibitory nucleic acids are described in Aagaard et al., Adv. Drug Delivery Rev. 59(2):75-86, 2007, and Burnett et al., Biotechnol. J. 6(9):1130-1146, 2011.

TNFα Inhibitor Antibodies

In some embodiments, the TNFα inhibitor is an antibody or an antigen-binding fragment thereof (e.g., a Fab or a scFv). In some embodiments, an antibody or antigen-binding fragment described herein binds specifically to any one of TNFα, TNFR1, or TNFR2.

In some embodiments, the TNFα inhibitor is DLX-105, e.g., the gel formulation.

In some embodiments, the TNFα inhibitor is adalimumab. Adalimumab is a recombinant human IgG1 monoclonal antibody specific for human tumor necrosis factor and is indicated for the treatment of various inflammatory diseases such as rheumatoid arthritis, Crohn's disease, and ulcerative colitis.

Adalimumab is currently delivered as an SC injection of 40 mg in 0.4-0.8 mL once every 1-2 weeks. It is sold in prefilled pen injectors for self-administration. The bioavailability is approximately 64% by SC injection, the half-life is approximately 2 weeks, and intracellular catabolism is the primary mode of elimination. Adalimumab must be refrigerated but can be temporarily stored at room temperature before use.

Adalimumab is a suitable therapeutic for delivery via ingestible device as described herein. It is currently available as a liquid, administered by self-injection, and, because adverse injection site reactions are not uncommon, patients may readily adopt an alternative dosage form. Lastly, the probability of acute reactions to overdose is low which, theoretically, could allow an increase in dose to compensate for lower bioavailability than SC injection.

In some embodiments, the therapeutic suitable for use with the devices and methods described herein is an IL-1 inhibitor. The term “IL-1 inhibitor” refers to an agent that decreases the expression of an IL-1 cytokine or an IL-1 receptor and/or decreases the ability of an IL-1 cytokine to bind specifically to an IL-1 receptor. Non-limiting examples of IL-1 cytokines include IL-1α, IL-1β, IL-18, IL-36α, IL-36β, IL-36γ, IL-38, and IL-33. In some examples, an IL-1 cytokine is IL-1α. In some examples, an IL-1 cytokine is IL-1β.

In some embodiments, an IL-1 inhibitory agent is an inhibitory nucleic acid, an antibody or fragment thereof, or a fusion protein. In some embodiments, the inhibitory nucleic acid is an antisense nucleic acid, a ribozyme, or a small interfering RNA.

Phosphodiesterase 4 (PDE4) Inhibitors

In some embodiments, the therapeutic suitable for use with the devices and methods described herein is a PDE4 inhibitor. The term “PDE4 inhibitor” refers to an agent which decreases PDE4 activity in vitro or in a mammalian cell, e.g., as compared to the level of PDE4 activity in the absence of the agent; and/or decreases the level of a PDE4 protein in a mammalian cell contacted with the agent, e.g., as compared to the same mammalian cell not contacted with the agent. A non-limiting example of PDE4 activity is the degradation of cAMP.

In some embodiments, a PDE4 inhibitor can be a small molecule (e.g., an organic, an inorganic, or bioinorganic molecule) having a molecule weight of less than 900 Daltons (e.g., less than 500 Daltons). In some embodiments, a PDE4 inhibitor can be an inhibitory nucleic acid.

Inhibitory Nucleic Acids of PDE4

In some embodiments, a PDE4 inhibitor can be an inhibitory nucleic acid. In some embodiments, the inhibitory nucleic acid can be an antisense nucleic acid, a ribozyme, and a small interfering RNA (siRNA).

Examples of modified nucleotides which can be used to generate an antisense nucleic acid include 5-fluorouracil, 5-bromouracil, 5-chlorouracil, 5-iodouracil, hypoxanthine, xanthine, 4-acetylcytosine, 5-(carboxyhydroxylmethyl) uracil, 5-carboxymethylaminomethyl-2-thiouridine, 5-carboxymethylaminomethyluracil, dihydrouracil, beta-D-galactosylqueosine, inosine, N6-isopentenyladenine, 1-methylguanine, 1-methylinosine, 2,2-dimethylguanine, 2-methyladenine, 2-methylguanine, 3-methylcytosine, 5-methylcytosine, N6-adenine, 7-methylguanine, 5-methylaminomethyluracil, 5-methoxyaminomethyl-2-thiouracil, beta-D-mannosylqueosine, 5′-methoxycarboxymethyluracil, 5-methoxyuracil, 2-methylthio-N6-isopentenyladenine, uracil-5-oxyacetic acid (v), wybutoxosine, pseudouracil, queosine, 2-thiocytosine, 5-methyl-2-thiouracil, 2-thiouracil, 4-thiouracil, 5-methyluracil, uracil-5-oxyacetic acid methylester, uracil-5-oxyacetic acid (v), 5-methyl-2-thiouracil, 3-(3-amino-3-N-2-carboxypropyl) uracil, (acp3)w, and 2,6-diaminopurine. Alternatively, the antisense nucleic acid can be produced biologically using an expression vector into which a nucleic acid has been subcloned in an anti sense orientation (i.e., RNA transcribed from the inserted nucleic acid will be of an antisense orientation to a target nucleic acid of interest).

Another example of an inhibitory nucleic acid is a ribozyme that has specificity for a nucleic acid encoding a PDE4 protein (e.g., specificity for a PDE4 mRNA). Ribozymes are catalytic RNA molecules with ribonuclease activity that are capable of cleaving a single-stranded nucleic acid, such as an mRNA, to which they have a complementary region. Thus, ribozymes (e.g., hammerhead ribozymes (described in Haselhoff and Gerlach, Nature 334:585-591, 1988)) can be used to catalytically cleave mRNA transcripts to thereby inhibit translation of the protein encoded by the mRNA. A ribozyme having specificity for a PDE4 mRNA can be designed based upon the nucleotide sequence of any of the PDE4 mRNA sequences disclosed herein. For example, a derivative of a Tetrahymena L-19 IVS RNA can be constructed in which the nucleotide sequence of the active site is complementary to the nucleotide sequence to be cleaved in a PDE4 mRNA (see, e.g., U.S. Pat. Nos. 4,987,071 and 5,116,742). Alternatively, a PDE4 mRNA can be used to select a catalytic RNA having a specific ribonuclease activity from a pool of RNA molecules. See, e.g., Bartel et al., Science 261:1411-1418, 1993.

An inhibitor nucleic acid can also be a nucleic acid molecule that forms triple helical structures. For example, expression of a PDE4 polypeptide can be inhibited by targeting nucleotide sequences complementary to the regulatory region of the gene encoding the PDE4 polypeptide (e.g., the promoter and/or enhancer, e.g., a sequence that is at least 1 kb, 2 kb, 3 kb, 4 kb, or 5 kb upstream of the transcription initiation start state) to form triple helical structures that prevent transcription of the gene in target cells. See generally Helene, Anticancer Drug Des. 6(6):569-84, 1991; Helene, Ann. N.Y. Acad. Sci. 660:27-36, 1992; and Maher, Bioassays 14(12):807-15, 1992.

Non-limiting examples of siRNAs targeting PDE4 are described in Takakura et al., PLosOne 10(12):e0142981, 2015; Watanabe et al., Cell Signal 27(7):1517-1524, 2015; Suzuki et al., PLos One 11(7):e0158967, 2016; Kai et al., Mol. Ther. Nucl. Acids 6:163-172, 2017. See, e.g., Cheng et al., Exp Ther Med 12(4):2257-2264, 2016; Peter et al., J. Immunol. 178(8):4820-4831, 2007; and Lynch et al., J Biol. Chem. 280:33178-33189, 2005. Additional examples of PDE4 inhibitory nucleic acids are described in U.S. Patent Application Publication Nos. 2010/0216703 and 2014/0171487, which are incorporated by reference in its entirety.

Heparins

In some embodiments, the therapeutic suitable for use with the devices and methods described herein is a heparin. In some embodiments, the heparin is a low molecular weight heparin.

An exemplary heparin is dalteparin. Dalteparin is a low molecular weight heparin. Like other low molecular weight heparins, dalteparin is used for prophylaxis or treatment of deep vein thrombosis, pulmonary embolism, venous thromboembolism, unstable angina, and non-Q-wave myocardial infarction.

Dalteparin is delivered as an SC injection of 2500-18000 units once or twice daily, depending on the reason for treatment. It is available in single-dose vials, multi-dose vials, and pre-filled syringes for self-administration by the patient. The maximum concentration in currently available formulations is 25,000 units/mL, and many formulations contain only water and HCl/NaOH for pH adjustment. The bioavailability is approximately 87% by SC injection, the half-life is approximately 3-5 hours, and it is primarily eliminated by the kidneys. Dalteparin is stable at room temperature and studies have demonstrated 30 days stability in commercial off-the-shelf syringes.

The primary risk of dalteparin overdose is uncontrolled hemorrhage at the site of injection. There are few cases of dalteparin overdose in the literature but, in most cases, the patients were discharged after observation without any intervention. One case describes self-administration of 360,000 units of dalteparin that was successfully managed with medical observation followed by discharge from the hospital with no notable sequelae. In the case of overdose, the action of dalteparin may be partially reversed by the administration of protamine sulfate.

Dalteparin is a suitable therapeutic for delivery via ingestible device as described herein. It is currently available as a liquid, administered by self-injection, and, because adverse injection site reactions are not uncommon, patients may readily adopt an alternative dosage form. The primary method of elimination is renal, so first-pass through the liver should not present an obstacle to using the drug delivery system. Lastly, the probability of acute reactions to overdose is low which, theoretically, could allow an increase in dose to compensate for lower bioavailability than SC injection. Dalteparin dose is normally specified as a single value based on the condition being treated and the weight range of the patient. Each weight range can span 10-15 kg, suggesting that precise dosing is not critical to achieving therapeutic effect.

Immune Modulators

In some embodiments, the therapeutic suitable for use with the devices and methods described herein is an immune modulator. As used herein, an “immune modulator” or “immune modulatory agent” is an agent that stimulates or suppresses the immune system and can help the body fight cancer, infection, or other diseases. The immune modulator can be a therapeutic agent that decreases the activation of an immune cell (e.g., a T cell, e.g., memory T cell), decreases the secretion or expression of a pro-inflammatory cytokine, decreases the recruitment or migration of T-lymphocytes (e.g., memory T lymphocytes), and/or increases the secretion or expression of an anti-inflammatory cytokine.

In some embodiments, an immune modulator is an antibody or antigen-binding fragment, a nucleic acid (e.g., inhibitory nucleic acid), a small molecule, a cancer vaccine, or a live biotherapeutic, such as a probiotic. In some embodiments, the immune modulator is a therapeutic agent used for the treatment of inflammatory bowel disease (IBD), for example, Crohn's Disease or Ulcerative Colitis (UC). Non-limiting immune modulators that are useful for treating or preventing inflammatory bowel disease include substances that suppress cytokine production, down-regulate or suppress self-antigen expression, or mask MHC antigens.

Examples of immune modulators include, without limitation: CHST15 inhibitors (e.g., STNM01); IL-6 receptor inhibitors (e.g., tocilizumab); IL-12/IL-23 inhibitors (e.g., PTG-200, ustekinumab and brazikumab); integrin inhibitors (e.g., vedolizumab and natalizumab); JAK inhibitors (e.g., tofacitinib); SMAD7 inhibitors (e.g., Mongersen); IL-13 inhibitors; IL-1 receptor inhibitors; TLR agonists (e.g., Kappaproct); stem cells (e.g., Cx601); 2-amino-6-aryl-5-substituted pyrimidines (see U.S. Pat.

In some embodiments of any of the devices or methods described herein, the therapeutic is an immune modulator. In some embodiments of any of the devices or methods described herein, the immune modulator is an IL-12/IL-23 inhibitor, a TNFα inhibitor, a CD40/CD40L inhibitor, an anti-integrin, or an IL-1 inhibitor. In some embodiments, the therapeutic is an immune modulator for use in a method of treating an inflammatory disease or condition that arises in a tissue originating from the endoderm in a subject, where the method includes orally administering to the subject an ingestible device loaded with the immune modulator, wherein the immune modulator is released by the device into the submucosa and/or the mucosa (e.g., into the lamina propria) of the gastrointestinal tract of the subject.

Advanced Therapeutic Medicinal Products (ATMPs) and Regenerative Medicine

In some embodiments of any of the devices or methods described herein, the therapeutic is a glycoprotein, enzyme, gene therapy, nude DNA, mRNA, viral vector, a somatic/stem cell therapy, an allogeneic or autologous stem cell therapeutic, or a medium conditioned by stem cells. In some embodiments, the therapeutic comprises a DNA or mRNA vaccine alone or with adjuvant therapy and may employ replication incompetent viruses for insertion.

In some embodiments, the therapeutic includes regulatory T cells (Treg cells). For example, from about 106 to about 109 (e.g., 106, 107, 108, or 109) autologous Treg cells (e.g., ova-specific T cells) can be delivered using the devices and methods described herein. Autologous Treg cells can be prepared by isolating peripheral blood mononuclear cells (PBMCs) from the subject's blood and then expanding ova-specific T cells by culturing the PBMCs in the presence of ovalbumin using Drosophila derived artificial antigen presenting cells transfected with specific stimulatory molecules. See, e.g., Brun, et al., Int Immunopharmacol., 2009, 9(5): 609-13. T cells can be cloned and Ova-Treg clones can be selected based on an ovalbumin-specific IL-10 production. A phase 1/2a study in 20 patients showed that a single injection of antigen-specific (ovalbumin) Treg cells was safe in CD and about 40% of the patients show a clinical response after treatment. See, e.g., Neurath, 2014, supra; and Desreumaux, et al., Gastroenterology, 2012, 143:1207-1217.

In some embodiments, stem cells are delivered using the devise and methods described herein. The delivery of stem cells can offer measurable therapeutic benefit as the stem cells have the ability to differentiate into numerous different cell types, and rejuvenate the surrounding area. In some embodiments, a population of cells is delivered that includes at least about 50% stem cells (at least about 55%, at least about 60%, at least about 65%, at least about 70%, at least about 75%, at least about 80%, at least about 85%, at least about 90%, at least about 95%, at least about 96%, at least about 97%, at least about 98%, or at least about 99% stem cells). The term “stem cell” is used herein to refer to a cell that is capable of differentiating into a two or more different cell types. As used herein, the term “a stem cell” may refer to one or more stem cells.

In some embodiments, the stem cells can be hematopoietic stem cells (HSC) capable of differentiating into different types of blood cells, including myeloid and lymphoid lineages of blood cells. HSC can be obtained from bone marrow, cord blood, or peripheral blood, and are commonly used for bone marrow transfusions in combination with chemotherapy to restart the immune system. HSC are CD34+ cells. Cell-surface markers can be identified by any suitable conventional technique, including, for example, positive selection using monoclonal antibodies against cell-surface markers.

The HSC used in the methods described herein can be, with respect to the subject, autologous or allogenic. HSC may have a high immunogenicity. As a result, if autologous HSC are not used, the HLA receptors of the donor and receiver must be matched. HSC can be harvested by mobilizing stem cells from the subject (autologous) or an HLA-matched donor (allogeneic) using granulocyte colony stimulating factor (GCSF) to promote the creation of HSC and their migration into the bloodstream. CD34+ cells can be collected from the peripheral blood or BM of the subject or donor, and then the cells can be cryopreserved until infusion or can be placed in a medium such as an alginate hydrogel. When stored for five days in an alginate-hydrogel in ambient temperature in an air-tight environment, stem cells showed a survival rate of 74-80%. For IBD, HSC therapy is preceded by chemotherapy, which removes the majority of the T-cells causing the inflammation, followed by administration of the HSC in the ingestible device.

In some embodiments, the stem cells used in the methods described herein are capable of differentiating into two or more different cell types other than blood cells. In some embodiments, the stem cells are capable of differentiating into cells of each of the three embryonic germ layers (i.e., endoderm, ectoderm, and mesoderm). As used herein, “capable of differentiating” means that a given cell, or its progeny, can proceed to a differentiated phenotype under the appropriate culture conditions. The capacity of the cells to differentiate into at least two cell types can be assayed by methods known in the art.

Non-limiting examples of stem cells include embryonic stem cells or adult stem cells such as mesenchymal stem cells (MSC) (also can be referred to as mesenchymal stromal cells) or other multipotent stem cells; endothelial progenitor cells; stem cells from a particular tissue or organ such as intestinal stem cells, adipose stem cells, or testes stem cells; or induced pluripotent stem cells (iPSC). In some embodiments, stem cells from a particular tissue also can be classified as MSC.

In some embodiments, the stem cells are MSC, which can differentiate into bone, muscle, cartilage, or adipose type cells. MSC can down-regulate inflammation and have a strong immunoregulatory potential. MSC can be obtained from various tissues, including from, for example, bone marrow, placenta, amniotic fluid, Wharton's jelly, amniotic membrane, chorionic villi, umbilical cord, umbilical cord blood, adipose tissue, dental pulp, synovial membrane, or peripheral blood. Depending on the source of MSC and the stemness (i.e., multipotency), the MSC can express a variety of different markers, including, for example, one or more of CD105, CD73, CD90, CD13, CD29, CD44, CD10, Stro-1, CD271, SSEA-4, CD146, CD49f, CD349, GD2, 3G5, SSEA-3, SISD2, Stro-4, MSCA-1, CD56, CD200, PODX1, Sox11, or TM4SF1 (e.g., 2 or more, 3 or more, 4 or more, 5 or more, 6 or more, 7 or more, 8 or more, 9 or more, or 10 or more of such markers), and lack expression of one or more of CD45, CD34, CD14, CD19, and HLA-DR (e.g., lack expression of two or more, three or more, four or more, or five or more such markers). In some embodiments, MSC can express CD105, CD73, and CD90. In some embodiments, MSC can express CD105, CD73, CD90, CD13, CD29, CD44, and CD10. In some embodiments, MSC can express CD105, CD73, and CD90 and one or more stemness markers such as Stro-1, CD271, SSEA-4, CD146, CD49f, CD349, GD2, 3G5, SSEA-3. SISD2, Stro-4, MSCA-1, CD56, CD200, PODX1, Sox11, or TM4SF1. In some embodiments, MSC can express CD105, CD73, CD90, CD13, CD29, CD44, and CD10 and one or more stemness markers such as Stro-1, CD271, SSEA-4, CD146, CD49f, CD349, GD2, 3G5, SSEA-3. SISD2, Stro-4, MSCA-1, CD56, CD200, PODX1, Sox11, or TM4SF1. See, e.g., Lv, et al., Stem Cells, 2014, 32:1408-1419.

The MSC used in the methods described herein can be, with respect to the subject, autologous or allogenic. MSC have low immunogenicity due to a dearth of HLA receptors on their surface. As a result, allogenic MSC therapy is a far more viable option for patients. Furthermore, MSC are able to downregulate the immune system, which can modulate the inflammation caused in many autoimmune disorders.

In some embodiments, MSC are commercially available. See, e.g. Prochymal® from Osiris Therapeutics.

In some embodiments, MSC can be harvested from bone marrow by ex vivo culture of the adherent cell fraction of bone marrow aspirates. The solid surface to which the MSC adhere can be a plastic material such as a polystyrene plate, optionally coated with poly-D-Lysine, laminin, or other reagent.

In some embodiments, the stem cells can be PF-05285401 cells (Multistem® cells), which are human stem cells obtained from adult bone marrow or other nonembryonic tissue sources. Multistem® cells are commercially available from Athersys Inc.

In some embodiments, MSC can be harvested from adipose tissue such as brown or white adipose tissue from subcutaneous, omental/visceral, mammary, gonadal, or other adipose tissue site. For example, the MSC can be harvested from subcutaneous white adipose tissue such as that isolated from liposuction. The cells can be harvested by mincing the adipose tissue and washing to remove blood. If the adipose tissue is obtained from a liposuction procedure, mincing is not required. The adipose tissue can be incubated with an enzyme such as Type I collagenase, and the stromal vascular fraction (SVF), which contains a variety of cell types including MSC, can be recovered and the MSC selected from the mixed cell population by adherence to a solid surface such as plastic cell culture surface optionally coated as described above. Yield of MSC from adipose tissue is up to 300-fold higher than the yield of MSC from bone marrow. See, e.g., Fellows, et al., Front Genet. 2016, 7:213; Lechanteur, et al., J Transl Med. 2016; 14: 145. In some embodiments, the stem cells can be autologous adipose derived stem cells such as Cx401 cells.

In some embodiments, the MSC can be expanded in cultured, e.g., passaged at least two times, at least three times, at least four times, at least five times, at least six times, at least seven times, at least eight times, at least nine times, or at least ten times. In some embodiments, cells can be passaged more than three times to improve the homogeneity of the cell phenotype in the cell population. In some embodiments, the cells can be expanded in culture until needed, so long as the homogeneity of the cell phenotype is improved and differential capacity is maintained. See Martin, et al., Cytotherapy, 2016, 18(5): 613-620 for methods of culturing MSCs.

The MSC can be cryopreserved until formulated for the ingestible device or can be placed in a medium such as an alginate hydrogel. The viability of MSC cells stored in alginate hydrogels after 50 days at ambient temperature is 80%.

In some embodiments, the MSC can be coated with antibodies, e.g., anti-vascular cell adhesion molecule-1 (e.g., VCAM-1) antibodies or anti-addressin antibodies, to improve, for example, their ability to target and hone into inflamed lesions in the GI tract. See, e.g., Ko, et al., Mol Ther. 2010, 18(7): 1365-1372.

In some embodiments, human iPSCs can be generated from adult somatic cells (e.g., fibroblasts, keratinocytes, dental pulp cells, cord blood, or peripheral blood mononuclear cells) or MSC. iPSCs can be generated using retroviral or non-retroviral methods. See, for example, Loh, et al., Blood 2009, 113:5476-5479, Okita, et al., Nat Methods. 2011, 8(5):409-12, or Okita, et al., Stem Cells, 2013, 31(3): 458-466. In some embodiments, p53 suppression and nontransforming L-Myc can be used to generate human induced pluripotent stem cells (iPSCs) with episomal plasmid vectors encoding OCT3/4, SOX2, KLF4, and LIN28. In some embodiments, adult somatic cells can be transduced with retroviruses encoding four pluripotency factors (SOX2, KLF4, c-MYC, and OCT4). Fully reprogrammed iPSCs have similar properties to embryonic stem cells (ESCs). Patient's cells can be used to derive iPSCs, which can then be induced to undergo differentiation into various types of somatic cells, all with the same genetic information as the patient. See, Azizeh-Mitra, et al., Stem Cells Int. 2016; 6180487. In other embodiments, allogenic cells are used to derive iPSCs.

In some embodiments, the stem cells can be intestinal stem cells (ISC), which can differentiate into intestinal cell subtypes such as globet cells, Paneth cells, and enterocytes. ISC are located at the crypt base within the intestine and can be positive for one or more markers such as Musashi-1 (Msi-1), Ascl2, Bmi-1, Doublecortin and Ca2+/calmodulin-dependent kinase-like 1 (DCAMKL1), and Leucin-rich repeat-containing G-protein-coupled receptor 5 (Lgr5). See, e.g., Mohamed, et al., Cytotechnology, 2015 67(2): 177-189. In addition, ISC or crypts can be used to produce intestinal organoids using a biodegradable scaffold (e.g., poly-glycolic acid), growth factors such as epidermal growth factor (EGF), R-spondin, Jagged-1 peptide, or Noggin, and extracellular matrix. In some embodiments, mesenchymal cells are included in the culture to support the growth. The intestinal organoid can include a central lumen lined by a villus-like epithelium. See, e.g., US20160287670A1 and WO2015183920A2. Pre-clinical studies have demonstrated the intestinal organoid efficacy in differentiating into all GI cell lineages and regrowing parts of the intestine, muscle layer included. See, Agopian, et al., J Gastrointest Surg., 2009, 13(5):971-82; Kuratnik and Giardina, Biochem Pharmacol., 2013, 85:1721-1726; and Belchior et al., Semin Pediatr Surg., 2014, 23:141-149.

In some embodiments, the stem cells can be allogeneic adipose-derived stem cells (ASC) such as ALLO-ASC cells or expanded ASC (eASC) (e.g., Cx601 cells). See, for example, Panes et al., Lancet; 2016, 388: 1281-90; and U.S. Patent Publication No. 20120020930. Cx601 cells are commercially available from TiGenix. Cx601 cells have been used for treating complex perianal fistulas in Crohn's disease patients. For example, Cx601 cells can be used for treating complex perianal fistulas with non-active/mildly active luminal Crohn's disease. ALLO-ASC cells are commercially available from Anterogen Co., Ltd., and have been used for treating Crohn's disease.

In some embodiments of any of the devices or methods described herein, the therapeutic is a live yeast, bacteriophage or prophage (i.e., the genetic material of a bacteriophage incorporated into the genome of a bacterium or existing as an extrachromosomal plasmid of the bacterium, and able to produce phages if specifically activated). The bacteriophage can be lytic or lysogenic. In some embodiments, the bacteriophage can infect bacteria commonly found in the GI tract. For example, the bacteriophage can infect one or more, two or more, three or more, four or more, five or more, six or more, seven or more, eight or more, nine or more, or ten or more species of bacteria within the GI tract. See, for example, Wang, et al., Inflamm Bowel Dis. 2015; 21(6): 1419-1427. In some embodiments, the bacteriophage can be lytic bacteriophage and infect one or more detrimental bacterial species in the GI tract to reduce the detrimental species in the GI tract. For example, the bacteriophage can infect two or more, three or more, four or more, five or more, six or more, or seven or more detrimental bacterial species. In some embodiments, bacteriophage can be a member of the families from the order Caudovirales such as Siphoviridae, Myroviridae, Podoviridae, or Microviridae. See, e.g., Babickova and Gardlik, World J. Gastroentrol. 2015; 21(40): 11321-11330. In some embodiments, the bacteriophage can include one or more of bacteriophage K (such as ATCC strain 19685-B 1), bacteriophage 17 (such as ATCC strain 23361-B 1), and Stab8. See, e.g., WO2016172380A1. In some embodiments, one or more bacteriophages, and one or more probiotics or prebiotics, optionally in combination with an antibiotic, are used to reduce detrimental bacterial species.

For therapeutics containing stem cells, the cells can be formulated to include one or more additional compounds such as a growth factor, a plurality of different growth factors, an anti-inflammatory agent, an immunosuppressive agent, a biological agent, an antibiotic, an anti-diarrheal agent, an adhesive, or other compounds that affect cell differentiation and/or proliferation. For example, the live biotherapeutic can be formulated to include one or more of the following: granulocyte colony-stimulating factor (G-CSF); an anti-inflammatory agent such as an agent comprising mesalamine; an immunosuppressive agent such as 6-mercaptopurine or azathioprine; a biological agent such as infliximab (Remicade®); an antibiotic, an antidiarrheal agent such as diphenoxylate, loperamide, and codeine; or an adhesive such as fibrin.

In some embodiments, the therapeutic can include glycoproteins, for example, a granulocyte-macrophage colony-stimulating factor (GM-CSF). Pharmaceutical analogs of naturally occurring GM-CSF include sargramostim and molgramostim Nartograstim, myelopoietins, circularly permuted G-CSF sequences, and SB247464 are among the known mimetics of G-CSF.

In some embodiments, the therapeutic can include bacteriophage or prophage that are genetically modified to produce one or more products that are anti-inflammatory and/or that can enhance intestinal barrier function.

In some embodiments, the ingestible device includes a targeted antimicrobial in which RNA-guided nucleases (RGNs) targeting specific DNA sequences within a target bacteria can be efficiently delivered to microbial populations using bacteriophage or bacteria carrying plasmids. For example, a targeted antimicrobial can couple a phage vector with the CRISPR (clustered regularly interspaced short palindromic repeats)/Cas system (e.g., the biological nanobots from Eligo Bioscience (Eligobiotics)). The biological nanobots can be composed of a capsid from a bacteriophage virus (modified to not multiply) that can deliver the CRISPR/Cas9 system into the targeted bacteria, resulting in the targeted bacteria being killed by cleavage of the bacterial genome by Cas9 enzyme within a predetermined pathogenic sequence. See, for example, WO2017009399A1 and Citorik, et al., Nat Biotechnol., 2014, 32(11): 1141-1145.

For therapeutics containing bacteriophage or prophage, the bacteriophage or prophage can be lyophilized, or can be in saline or other pharmaceutical carrier. Lyophilized phage can be incorporated into a solid or semi-solid formulation without materially reducing efficiency, and can be temperature stable up to 55° C. with a shelf life of 14 months. Liquid formulations of phage can be stored at 4° C.

Oral Vaccines

In some embodiments, the therapeutic suitable for use with the devices and methods described herein is an oral vaccine. As used herein, an “oral vaccine” is one or more antigens administered orally which can induce an immune response against one or more diseases caused by pathogens in the mucosal sites within the GI tract. The antigen in an oral vaccine can induce an immune response associated with the production of immunoglobulins both systemically (IgG) and locally at the mucosa (secretory IgA (sIgA)) (for review, see Brandtzaeg, Curr. Top. Microbiol. Immunol., 146:13-25 (1989)). Oral administration of vaccine antigens can induce immune responses both at the induction sites and other effector sites within the mucosal immune compartments through the dissemination of sensitized lymphoid cells from the induction sites. In some embodiments, the use of needle-free injection of an oral vaccine as compared to a parenteral vaccine improves patient compliance and safety. In some embodiments, the intact and active antigen is delivered to the intestine. In some embodiments, successful delivery of an oral vaccine includes protecting the antigens against the harsh stomach environment (e.g., low pH) and the hydrolytic enzymes present in the GI tract that can degrade the antigens. As such, in some embodiments, encapsulation of an oral vaccine within the ingestible device obviates the need for higher doses of the antigens that can result in immunological tolerance to the vaccine. Encapsulation of an oral vaccine within the ingestible device can further prevent antigen dilution over the large surface area of the GI tract. The oral vaccine can be released from the ingestible device at desired locations within the GI tract, for example, in the small intestine where the majority of absorption processes occur, thereby solving the temporal limitation challenge for absorption of the vaccine formulations.

In some embodiments, the oral vaccine comprises one or more antigens in a mixture selected from a live-attenuated pathogen, an inactivated pathogen, a live pathogen, a protein subunit of a pathogen, a carbohydrate subunit of a pathogen, and a carbohydrate-polysaccharide conjugate of a pathogen. In some embodiments, the oral vaccine antigen is a live-attenuated pathogen. In some embodiments, the antigen is an inactivated pathogen. In some embodiments, the antigen is a live pathogen. In some embodiments, the antigen is a protein subunit of a pathogen. In some embodiments, the antigen is a carbohydrate subunit of a pathogen. In some embodiments, the antigen is a carbohydrate-polysaccharide conjugate of a pathogen. In some embodiments, the oral vaccine formulation comprises one or more adjuvants. As used herein, an “adjuvant” is a substance added to a vaccine to enhance the immunogenicity of an antigen. Suitable adjuvants for use in the oral vaccine formulations of the present disclosure include any adjuvant known by one of skill in the art that can be used to enhance the immunogenicity of an antigen. In some embodiments, the adjuvants are particulates of aluminum salts. In some embodiments, the adjuvants are oil-in-water emulsions. In some embodiments, the adjuvants are toll-like receptor (TLR) ligands. In some embodiments, the adjuvants are immuno-stimulating complexes (ISCOMs). In some embodiments, the adjuvants are QS-21. In some embodiments, the adjuvants are AS03. In some embodiments, the adjuvants are AS04. In some embodiments, the adjuvants are virosomes. In some embodiments, the adjuvants are MF59® (for review, see Di Pasquale et al., Vaccines, 3; 320-343 (2015)).

In some embodiments, the oral vaccine is used to induce an immune response against a viral pathogen. Non-limiting examples of viral pathogens include strains of adenovirus, Chikungunya virus, coronavirus, dengue virus, Ebola virus, enterovirus D68 (EV-D68), enterovirus 71 (EV-71), hepatitis virus, herpes simplex virus, human immunodeficiency virus (HIV), human papilloma virus (HPV), influenza virus, Japanese encephalitis virus, measles virus, mumps virus, Nipah virus, norovirus (Norwalk virus), poliomyelitis virus, rabies virus, respiratory syncytial virus (RSV), rotavirus, rubella virus, tick-borne encephalitis virus, varicella zoster virus, yellow fever virus and Zika virus. In some embodiments, the oral vaccine is used to induce an immune response against a bacterial pathogen. Non-limiting examples of bacterial pathogens include Bordetella pertussis, Campylobacter jejuni, Clostridium difficile, Clostridium tetani, Corynebacterium diphtherias, enterotoxigenic Escherichia coli, Group B Streptococcus (GBS), Haemophilus influenzae type b (Hib), Helicobacter pylori, Mycobacterium tuberculosis (TB), Neisseria meningitidis, Salmonella typhi, Salmonella enterica, nontyphoidal Salmonella species, Shigella, Vibrio cholerae, Staphylococccus aureus, Streptococcus pneumoniae, Streptococcus pyrogenes. In some embodiments, the oral vaccine is used to induce an immune response against a parasitic pathogen. Non-limiting examples of parasitic pathogens include human hookworm, leishmania, plasmodium, schistosomes and Trypanosoma cruzi.

In some embodiments, the oral vaccine is selected from oral vaccines including Sabin Live OPV (for polio); Vivotif® (for typhoid fever); Dukoral® (for cholera); Vaxchora® (for cholera); Rotarix® (for gastroenteritis); RotaTeq® (for gastroenteritis), live Adenovirus oral vaccine (for acute respiratory disease), BNT162 from Pfizer, BioNTech (for SARS-CoV-2), mRNA-1273 from Moderna (for SARS-CoV-2), AZD1222 from AstraZeneca (for SARS-CoV-2), CoronaVac from Sinovac (for SARS-CoV-2), and JNJ-78436735 from Johnson & Johnson (for SARS-CoV-2).

Antibody-Drug Conjugates

In some embodiments, the therapeutic agent is delivered to target cells or tissues as a conjugate covalently linked to a monoclonal antibody (mAb), a fragment of an antibody, or biosimilars thereof. In some embodiments, the therapeutic agent is linked to an antibody. The resulting pharmaceutical entity, commonly known as an antibody-drug conjugate (ADC), can enable the delivery of a therapeutic agent to target cells expressing an antigen recognized by the antibody. In some embodiments, undesirable off-target toxicity is reduced. In some embodiments, the therapeutic index of the therapeutic agent is improved. In some embodiments, the antibody of an ADC binds to one antigen. In some embodiments, the antibody of an ADC binds to two different antigens (i.e., bispecific). In some embodiments, the antibody of an ADC binds to more than two different antigens (i.e., multi-specific). In some embodiments, the therapeutic agent of an ADC is a small molecule drug. In some embodiments, the therapeutic agent of an ADC is a peptide drug. In some embodiments, the therapeutic agent of an ADC is an imaging agent. In some embodiments, the therapeutic agent of an ADC is a radiolabeled drug. In some embodiments, the ADC is used as a treatment for cancer. In some embodiments, the ADC is used as an immune modulator. In some embodiments, the ADC is used as a treatment for an infectious disease (see for example, Liu et al., Expert Opin. Biol. Ther., 16:591-593 (2016)). Examples of ADC drugs include, but are not limited to, gemtuzumab ozogamicin (Mylotarg®), brentuximab vedotin (Adcetris®), trastuzumab emtansine (Kadcyla®), inotuzumab ozogamicin (Besponsa®), polatuzumab vedotin-piiq (Polivy®), enfortumab vedotin (Padcev®), trastuzumab deruxtecan (Enhertu®), and sacituzumab govitecan (Trodelvy®).

In some embodiments, the therapeutic agent is linked to an antibody or an antibody fragment via a chemical linker. In some embodiments, the chemical linker is stable during systemic circulation, but releases the therapeutic agent in or near target cells. In some embodiments, the linker is cleavable. In some embodiments, the cleavable linker is cleaved by enzymes. In some embodiments, the cleavable linker is cleaved by changes in pH. In some embodiments, the cleavable linker is cleaved by changes in redox potential. In some embodiments, the linker is non-cleavable. In some embodiments, the drug-linker is linked to an antibody or an antibody fragment via a surface-exposed native amino acid residue of an antibody. In some embodiments, the native amino acid is lysine. In some embodiments, the native amino acid is cysteine. In some embodiments, the the native amino acid is tyrosine. In some embodiments, the native amino acid is glutamine. In some embodiments, the drug-linker is linked to an antibody or an antibody fragment via a non-native amino acid residue engineered into specific locations of the antibody. In some embodiments, the non-native amino acid isp-azido-L-phenylalanine (pAzF). In some embodiments, the non-native amino acid is p-azidomethyl-L-phenylalanine (pAMF). In some embodiments, the non-native amino acid is selenocysteine (Sec). In some embodiments, the non-native amino acid is azido-lysine. In some embodiments, the non-native amino acid is a cyclopropene derivative of lysine (CypK).

In some embodiments, the conjugation site is non-specific, wherein the ADC molecules comprise drugs conjugated to different locations on the antibody molecules. In some embodiments, the conjugation sites are specific, wherein the ADC molecules comprise drugs conjugated to the same locations of each antibody molecule. Since not every possible conjugation site of each antibody molecule or antibody fragment are conjugated to drug molecules, the average drug-to-antibody ratio (DAR) is commonly used to describe the amount of drug molecules relative to the amount of antibody molecules present in an ADC mixture on a molar basis. In some embodiments, the average DAR in an ADC mixture is about 1:1. In some embodiments, the average DAR in an ADC mixture is about 2:1. In some embodiments, the average DAR in an ADC mixture is about 3:1. In some embodiments, the average DAR in an ADC mixture is about 4:1. In some embodiments, the average DAR in an ADC mixture is about 5:1. In some embodiments, the average DAR in an ADC mixture is about 6:1. In some embodiments, the average DAR in an ADC mixture is between about 1:1 and about 2:1. In some embodiments, the average DAR in an ADC mixture is between about 2:1 and about 3:1. In some embodiments, the average DAR in an ADC mixture is between about 3:1 and about 4:1. In some embodiments, the average DAR in an ADC mixture is between about 4:1 and about 5:1. In some embodiments, the average DAR in an ADC mixture is between about 5:1 and about 6:1.

In some embodiments, the therapeutic agent is linked to an antibody fragment. The relatively large size of an intact antibody scaffold (e.g., approximately 150,000 daltons) can present several issues for an ADC based on intact antibodies, including poor tumor penetration, high systemic accumulation, and slow clearance profiles. The use of other scaffolds such as antibody fragments or antibody mimics for targeted delivery of therapeutic agents has been explored (see, e.g., Richards, Drug Discov. Today Technol., 30:35-46 (2018)). In some embodiments, the antibody fragment is a fragment antigen binding (Fab) domain. In some embodiments, the antibody fragment is a F(ab′)₂ domain. In some embodiments, the F(ab′)₂ domain is obtained by treating an immunoglobulin monomer with the enzyme papain. In some embodiments, the antibody fragment is a Fab′ fragment. In some embodiments, the Fab′ fragment is obtained by mild reduction of a F(ab′)₂ domain. In some embodiments, the antibody fragment is a single chain fragment variable (scFv) domain. In some embodiments, the scFv domain comprises fused variable regions of the heavy and light chains of an antibody. In some embodiments, the antibody fragment is a diabody. In some embodiments, the diabody is comprised of two scFv fragments bivalent complex. In some embodiments, the diabody is a bivalent homodimer complex. In some embodiments, the diabody is a bivalent heterodimer, bispecific complex. In some embodiments, the antibody fragment is an antibody fragment crystalizable (Fc) domain. The Fc domain of an antibody is about 50,000 daltons in molecular weight, and is the base portion of an antibody that binds to a corresponding Fc receptor on the surface of certain types of immune cells (e.g., macrophages, neutrophils, eosinophils, dendritic cells, B cells, natural killer cells, and mast cells) and some proteins in the complement system. Conjugation of the therapeutic agent to an Fc domain can significantly increase its serum half-life and thereby prolonging its therapeutic activity due to the increase in the overall molecular weight of the conjugate and engagement in the neonatal Fc receptor (FcRn)-mediated recycling process. The Fc domain can also slow down renal clearance of the therapeutic agent, and may help improve its solubility and stability (see, e.g., Pechtner et al. Prim. Health Care, 7:1-5 (2017)). Attachment of an Fc domain to a therapeutic agent can also direct the therapeutic agent to target immune cells via interactions with the corresponding Fc receptors. In some embodiments, the Fc-conjugated therapeutic agent is etanercept (Enbrel®). In some embodiments, the Fc-conjugated therapeutic agent is belatacept (Nulojix®). In some embodiments, the Fc-conjugated therapeutic agent is aflibercept (Eylea®). In some embodiments, the Fc-conjugated therapeutic agent is dulaglutide (Trulicity®).

In some embodiments, targeted delivery of a therapeutic agent can be achieved via conjugation to small immunoproteins (SIPS). In some embodiments, the SIPS comprises scFv fragments fused to an immunoglobulin-derived constant region. In some embodiments, targeted delivery of a therapeutic agent can be achieved via conjugation to synthetic antibody scaffolds. Examples of synthetic antibody scaffolds include, but are not limited to, affibodies, which are small (˜7,000 daltons) 3-helix proteins derived from the Z-domain of Staphylococcus protein-A; monobodies, which are small (˜10,000 daltons) cysteine-free scaffolds based on the 10^th type-III fibronectin; centyrins, which are structurally similar to monobodies but are based on the Fn3 domain of Tenascin C instead of fibronectin; DARPins, which are designed scaffolds based on Akyrin repeats; and knottins, which are designed knotted peptides with 30-50 amino acid residue and three or more disulfide bridges.

Tables 16 and 17 show illustrative dosing regimens for different therapeutics agents delivered with ingestible devices described herein. For the purposes of the tables, the ingestible devices have two different payload sizes: 200 μL in 00-sized device and 400 μL in 000-sized device. The dosing regimens were generated using a model that accounts for different therapeutic agent characteristics (e.g., approved dose, approved dosing frequency, and bioavailability via intravenous (IV), subcutaneous (SC) or intramuscular (IM) administration). The model assumes each drug can be formulated for the device to a maximum concentration of 175 mg/mL. Given the payload size, therapeutic agent characteristics, and a 175 mg/mL drug concentration, bioavailability benchmarks (“Required Bioavailability”) for different dosing regimens (“PGN Regimen”) are shown in the table. For example, as shown in Table 16 for adalimumab, an approved 40 mg subcutaneous injection provides an effective dose of 25.6 mg given adalimumab's subcutaneous bioavailability of 64%. This dose is approved in the U.S. for subcutaneous administration every two weeks. Administration of adalimumab at a concentration of 175 mg/mL using a 000-sized ingestible device with a payload of 400 μL achieves the same effective dose when administered weekly (qwk) given a bioavailability of 18.3%. Likewise, using a 00-sized ingestible device with a payload of 200 μL achieves the same effective dose when administered daily (qd) given a bioavailability of 5.2%. If, for example, the bioavailability for the ingestible device is fixed at 25% for a therapeutic agent, similar calculations can be used to calculate the required drug concentration to achieve a desired effective dose.

Table 17 provides the same information for a different set of therapeutic agents. For non-approved therapeutic agents, dose information was sourced from publicly available clinical trial information. Also, for dose based on patient weight, the assumed weight is 70 kg.

Trans-Epithelial Administration

In some embodiments, the method comprises trans-epithelial administration of a therapeutic agent to the GI tract of the subject. In some embodiments, the method provides systemic uptake of the therapeutic agent of about 10% to about 99%, for example, at least about 10%, at least about 15%, at least about 20%, at least about 25%, at least about 30%, at least about 35%, at least about 40%, at least about 45%, at least about 50%, at least about 55%, at least about 60%, at least about 65%, at least about 70%, at least about 75%, at least about 80%, at least about 85%, or at least about 90%, relative to intravenous or subcutaneous administration of the same amount of the therapeutic agent. In some embodiments, the same amount of therapeutic agent is an approved or commercially-available dose. In some more particular embodiments, the systemic uptake is at least about 10% relative to intravenous or subcutaneous administration of the same amount of the therapeutic agent. In other embodiments, the systemic uptake is at least about 15% relative to intravenous or subcutaneous administration of the same amount of the therapeutic agent. In yet other embodiments, the systemic uptake is at least about 20% relative to intravenous or subcutaneous administration of the same amount of the therapeutic agent. In yet other embodiments, the systemic uptake is at least about 25% relative to intravenous or subcutaneous administration of the same amount of the therapeutic agent. In yet other embodiments, the systemic uptake is at least about 30% relative to intravenous or subcutaneous administration of the same amount of the therapeutic agent. In yet other embodiments, the systemic uptake is at least about 35% relative to intravenous or subcutaneous administration of the same amount of the therapeutic agent. In yet other embodiments, the systemic uptake is at least about 40%, or even higher, relative to intravenous or subcutaneous administration of the same amount of the therapeutic agent.

In some embodiments, the trans-epithelial administration provides an area under a curve (AUC_TE) of the therapeutic agent in systemic circulation versus time of about 10% to about 99%, for example, at least about 10%, at least about 15%, at least about 20%, at least about 25%, at least about 30%, at least about 35%, at least about 40%, at least about 45%, at least about 50%, at least about 55%, at least about 60%, at least about 65%, at least about 70%, at least about 75%, at least about 80%, at least about 85%, or at least about 90% as the AUC obtained when the same amount of the therapeutic agent is delivered intravenously (to the same subject, or to a population of subjects) (AUC_IV). In some embodiments, the same amount of therapeutic agent is an approved or commercially-available dose. In some more particular embodiments, the area under a curve (AUC_TE) of the therapeutic agent in systemic circulation versus time is at least about 15% of the AUC obtained when the same amount of the therapeutic agent is delivered intravenously (AUC_IV). In some other embodiments, the area under a curve (AUC_TE) of the therapeutic agent in systemic circulation versus time is at least about 20% of the AUC obtained when the same amount of the therapeutic agent is delivered intravenously (AUC_IV). In some other embodiments, the area under a curve (AUC_TE) of the therapeutic agent in systemic circulation versus time is at least about 25% of the AUC obtained when the same amount of the therapeutic agent is delivered intravenously (AUC_IV). In some other embodiments, the area under a curve (AUC_TE) of the therapeutic agent in systemic circulation versus time is at least about 30% of the AUC obtained when the same amount of the therapeutic agent is delivered intravenously (AUC_IV).

In some embodiments, the same amount of therapeutic agent is an approved or commercially-available dose. In some embodiments, the AUC is the mean AUC.

In some embodiments, the trans-epithelial administration provides a maximum plasma concentration ((C_max)_TE) of the therapeutic agent in systemic circulation versus time of about 10% to about 99%, for example, at least about 10%, at least about 15%, at least about 20%, at least about 25%, at least about 30%, at least about 35%, at least about 40%, at least about 45%, at least about 50%, at least about 55%, at least about 60%, at least about 65%, at least about 70%, at least about 75%, at least about 80%, at least about 85%, or at least about 90% as the AUC obtained when the same amount of the therapeutic agent is delivered intravenously (to the same subject, or to a population of subjects) ((C_max)_IV). In some embodiments, the same amount of therapeutic agent is an approved or commercially-available dose. In some more particular embodiments, the maximum plasma concentration ((C_max)_TE) of the therapeutic agent in systemic circulation versus time is at least about 15% of the AUC obtained when the same amount of the therapeutic agent is delivered intravenously ((C_max)_IV). In some other embodiments, the maximum plasma concentration ((C_max)_TE) of the therapeutic agent in systemic circulation versus time is at least about 20% of the AUC obtained when the same amount of the therapeutic agent is delivered intravenously ((C_max)_IV).

Inflammatory Conditions or Diseases

In some embodiments, the condition or disease that can be treated with the methods and devices disclosed herein is an inflammatory condition or disease. The presently described devices and methods are based, in part, on the unexpected discovery that administration of an immune modulator into the tissue of a subject's gastrointestinal tract can result in the observation of pharmacodynamics effects in tissues beyond the site of deposition. For example, an immune modulator administered into the tissue (e.g., mucosa or submucosa) of a subject's gastrointestinal tract can result in one or more of the following: changes in anatomical features, including suppressed or reduced development, aggregation, or accumulation of one or more of intestinal lymphoid tissues, isolated lymphoid follicles (ILFs), or intestinal lymphoid aggregates; suppressed immune response, including fewer T cells measured in lymph nodes or lymph tissues (which results in greater T cells forced into circulation, i.e., blood); decreased differentiation of immune cells (e.g., as measured using histology or through the use of a sampling device, or using a sampling device); a decreased level of inflammatory cytokine levels (e.g., as measured using biopsy or through the use of a sampling device); decreased endoscopic scoring; and improved efficacy of treatment for IBD (e.g., using any of the clinical assessments of a treatment for IBD described herein) or other inflammatory conditions of the GI tract or endoderm (e.g., in the liver).

In some embodiments, the presently described devices provide for a higher concentration of α4β7 expressing cells in the periphery (e.g., blood) when an immune modulator is delivered into the GI tissue (e.g., mucosa or submucosa) of one or more parts of the GI tract distal to the stomach (e.g., the small or large intestine) as compared to when the same dose of the immune modulator is orally (without a device), intravenously, or subcutaneously administered. The presently described devices can, e.g., result in trafficked cells being forced out of the local gastrointestinal tissue (including the mucosa) and lymph system, and back into systemic circulation of a subject.

Accordingly, also provided herein are methods of treating a disease or condition that arises in a tissue originating from the endoderm. The endoderm forms the gastrointestinal tract, respiratory tract, endocrine glands, and organs, the auditory system and urinary system. Thus, the present disclosure includes compositions and devices for treating diseases and conditions found in the following tissues that originate from the endoderm (e.g., the stomach, the colon, the liver, the pancreas, the urinary bladder, the epithelial parts of the trachea, the lungs, the pharynx, the thyroid, the parathyroid, the intestines, and the gallbladder). Also provided herein are methods of treating a disease or a condition that arises in a tissue originating from the endoderm (e.g., any of the exemplary diseases or conditions that arise in a tissue originating from the endoderm described herein) that include depositing one or more immune modulators into the tissue of the small intestine using any of the devices or compositions described herein. In a preferred embodiment, the compositions, devices and methods are for treating inflammatory diseases and conditions found in the liver (e.g., NAFLD, NASH, or cirrhosis).

Non-limiting examples of an inflammatory disease or condition that arises in a tissue originating from the endoderm includes gastritis, celiac disease, hepatitis, alcoholic lever disease, fatty liver disease (hepatic steatosis), non-alcoholic fatty liver disease (NASH), cirrhosis, primary schlerosing cholangitis, pancreatitis, insterstitial cystitits, asthma, chronic obstructic pulmonary disease, pulmonary fibrosis, pharyngitis, thyroiditis, hyperthyroidism, parathyroiditis, nephritis, Hashimoto's disease, Addison's disease, Graves' disease, Sjögren syndrome, type 1 diabetes, pelvic inflammatory disease, auditory canal inflammation, tinnitus, vestibular neuritis, otitis media, auditory canal inflammation, tracheitis, cholestatic liver disease, primary biliary schlerosis, liver parenchyma, an inherited metabolic disorder of the liver, Byler syndrome, cerebrotendinous, xanthomatosis, Zellweger's syndrome, neonatal hepatitis, cystic fibrosis, ALGS (Alagilles syndrome), PFIC (progressive familial intrahepatic cholestasis), autoimmune hepatitis, primary biliary cirrhosis (PBC), liver fibrosis, NAFLD, portal hypertension, general cholestasis, such as in jaundice due to drugs or during pregnancy, intra- and extrahepatic cholestasis, such as hereditary forms of cholestasis, such as PFIC1, gall stones and choledocholithiasis, malignancy causing obstruction of the biliary tree, symptoms (scratching, pruritus) due to cholestasis/jaundice, chronic autoimmune liver disease leading to progressive cholestasis, and pruritus of cholestatic liver disease, duodenal ulcers, enteritis (radiation-, chemotherapy-, or infection-induced enteritis), diverticulitis, pouchitis, cholecystitis, and cholangitis. Additional examples of diseases and conditions that arise in a tissue originating from the endoderm are known in the art.

In some embodiments of any of the devices or methods described herein, the methods result in the introduction of the immune modulator to one or more of the following, or the PD effects of the immune modulator (e.g., any of the PD effects of immune modulators described herein) are detectable in one or more of the following: throughout or in part of the paraaortic lymph nodes, throughout or in part of the MALT, throughout or in part of the GALT, throughout or in part of the inferior and superior mesenteric lymph nodes, and in one or more sections or subsections of the subject's gastrointestinal tract that is different than the section or subsection of the subject's gastrointestinal tract where the immune modulator is released. In some embodiments of any of the devices or methods described herein, the devices or methods result in the presence or accumulation of the immune modulator in tissues or organs of the endoderm (e.g., the liver) at higher doses as compared to administration of the immune modulator orally (without a device), intravenously, or subcutaneously.

In some embodiments of any of the methods described herein, the methods do not result in (or do not result in a significant effect in) pharmacodynamics effect(s) (e.g., any of the clinical effects or measurements of an immune modulator described herein) outside of the paraaortic lymph nodes.

In some embodiments of any of the methods described herein, the methods do not result in (or do not result in a significant effect in) pharmacodynamics effect(s) (e.g., any of the clinical effects or measurements of an immune modulator described herein) outside of the MALT.

In some embodiments of any of the methods described herein, the methods do not result in (or do not result in a significant effect in) pharmacodynamics effect(s) (e.g., any of the clinical effects or measurements of an immune modulator described herein) outside of the GALT.

In any of the methods described herein, the subject can be any mammal (e.g., an animal model of any of the diseases described herein).

In some embodiments of any of the methods described herein, the method results in the suppression of the subject's immune response in one or more of the paraaortic lymph nodes.

In some embodiments of any of the methods described herein, the method results in the suppression of the subject's immune response in mucosa-associated lymphoid tissue (MALT).

In some embodiments of any of the methods described herein, the method results in the suppression of the subject's immune response throughout or in part of the gut-associated lymphoid tissue (GALT). For example, in some embodiments of any of the methods described herein, the method results in a reduction of T cells (e.g., any of the T cells described herein, e.g., memory T cells) in Peyer's patches and/or mesenteric lymph nodes found in the GALT. In some embodiments of any of the methods described herein, the method results in a decreased level of T cells (e.g., any of the types of T cells described herein or known in the art) in a section or subsection of the subject's gastrointestinal tract that is different than the section or subsection of the subject's gastrointestinal tract where the immune modulator is released.

In some embodiments of any of the methods described herein, the method results in the suppression or reduction in the development, the aggregation, or accumulation of one or more of intestinal lymphoid tissues, isolated lymphoid follicles (ILFs), or intestinal lymphoid aggregates in mucosa-associated lymphoid tissue (MALT). In some embodiments of any of the methods described herein, the method results in the suppression of the development of one or more of intestinal lymphoid tissues, isolated lymphoid follicles, or intestinal lymphoid aggregates in gut-associated lymphoid tissue (GALT). In some embodiments of any of the methods described herein, the method results in the suppression of the immune response in one or more sections or subsections of the subject's gastrointestinal tract that is different than the section or subsection of the subject's gastrointestinal tract where the drug is released.

In some embodiments of any of the methods described herein, the methods result in pharmacodynamics effects proximal (“upstream”) to the site of disease in the subject. For example, in some embodiments of any of the methods described herein, the immune modulator is deposited in the tissue of the small intestine (e.g., duodenum or jejunum), but pharmacodynamics effects of the immune modulator are observed in the liver. In some embodiments of any of the methods described herein, the immune modulator is deposited in the tissue of the small intestine (e.g., the duodenum or jejunum) and immune suppression is observed throughout the mesenteric lymph system and other systems of the paraaortic lymph nodes, including the hepatic lymph nodes of the celiac group of the preaortic lymph nodes (preaortic lymph nodes are part of the paraaortic lymph nodes). In some embodiments of any of the methods described herein, the immune modulator is deposited in the small intestine (e.g., duodenum, jejunum, or ileum) or colon (e.g., ascending colon, transverse colon, descending colon, rectum, or cecum), but pharmacodynamics effects of the immune modulator are throughout or in part of the MALT, GALT, Peyer's patches, mesenteric lymph nodes, paraaortic lymph nodes, or any of the other tissues originating from the endoderm described herein or known in the art, in the mammal.

In some embodiments of any of the methods described herein, the method results in a decreased level or a decreased level of activation of one or more of the following immune cells that participate in mucosal immune response in a mammal: microfold cells (M cells), antigen-presenting cells (e.g., B-lymphocytes, dendritic cells, and macrophages), and effector cells (e.g., T-lymphocytes).

Microfold cells (M cells) are found in the gut-associated lymphoid tissue (GALT) of the Peyer's patches in the small intestine. M cells allow for the transport of microbes and particles across the epithelial cell layer from the gut lumen to the lamina propria where interactions with immune cells can take place. M cells provide for the initiation of mucosal immunity responses on the apical membrane by delivering antigens to antigen-presenting cells.

Antigen-presenting cells (APCs) include B-lymphocytes, dendritic cells, and macrophages. B-lymphocytes, also called B-cells, can internalize antigen that binds to their B-cell receptor. Dendritic cells have the broadest range of antigen presentation and are necessary for activation of naïve T cells. Dendritic cells present antigen to both helper and cytotoxic T cells. Macrophages can be stimulated by T-cell secretion of interferon gamma. After this activation, macrophages are able to express major histocompatibility complex (MHC) class II and co-stimulatory molecules, and can present phagocytosed peptide fragments to helper T cells. The activation of macrophages can assist pathogen-infected macrophages in clearing the infection.

MHCs bind antigens derived from pathogens and display them on the cell surface for recognition by appropriate T-cells. MHC class I presents antigens from intracellular pathogens, such as viruses and bacteria. MHC class II presents antigens from phagocytosed/pinocytosed pathogens.

Effector cells, as used herein, include T-lymphocytes, including CD4⁺ (also called helper T cells), CD8⁺ (also called cytotoxic T cells), CD45Rb⁻ (more IL-10 and less TNFα in IBD) as compared with CD4⁺CD45Rb⁺, and CD44⁺ T cells. CD44 participates in lymphocytes activation, recirculation, and homing, and is an indicative marker for effector memory T cells.

In some embodiments of any of the devices or methods described herein, the therapeutic is an anti-Siglec-8 antibody. Anti-Siglec-8 antibodies deplete eosinophils and inhibit mast cells and may be useful for the treatment of eosinophilic gastritis and duodenitis. In some embodiments, the anti-Siglec-8 antibody is AK002 (lirentelimab). AK002 is a humanized, nonfucosylated IgG1 anti-Siglec-8 monoclonal antibody that depletes eosinophils through natural killer cell—mediated antibody-dependent cellular cytotoxicity (in the blood) and apoptosis (in tissues). See Dellon, Evan S., et al. “Anti-Siglec-8 Antibody for Eosinophilic Gastritis and Duodenitis.” New England Journal of Medicine 383.17 (2020): 1624-1634.

The ingestible device disclosed herein can be used to implement any of medical approaches 1-1140.

OTHER EMBODIMENTS

While certain embodiments have been provided, other embodiments are possible.

As an example, some embodiments have been described in which an ingestible device includes one or more pins. However, the disclosure is not limited in this sense. Rather, in such embodiments, any element having the appropriate shape and size, as well as being made of the appropriate material(s), may be used instead of (or, in some cases, in addition to) one or more of the pins.

As another example, while embodiments have been described in which the dispensable substance is released in a single stage. Other embodiments are possible. In some embodiments, multi-stage (e.g., two stage, three stage, four stage) release of the dispensable substance is used. Multi-staged release can be achieved, for example, via multiple elements (e.g., pins, plugs or the like) formed of different materials (e.g., different enteric materials) that degrade/dissolve erode under different conditions (e.g., different pH, temperature, enzyme concentration) present in different locations in the GI tract of a subject.

As an additional example, while embodiments have been described in which an ingestible device includes a seal or a coating, the disclosure is not limited in this sense. For example, in some embodiments, an ingestible device housing may be covered in one or more coverings, e.g., to seal the ingestible device and/or to hold two modules of the device together. In certain embodiments, an ingestible device may be sealed to prevent contaminants from entering the ingestible device prior to administration to a subject (e.g., during storage of the device) or after administration to a subject (e.g., during transit through the stomach), or to prevent the contents of the ingestible device (e.g., a dispensable substance) from exiting the ingestible device before desired (e.g., prior to triggering). In certain embodiments, an ingestible device is assembled from two modules: one module contains the dispensable substance (“drug module”), while the other module contains the drive force generator and the drive coupling (“drive module”). One or more coverings can be used to partially or wholly join and/or seal the two modules after they are assembled together to form an ingestible device. In some embodiments, one or more coverings cover the entirety of the housing of the ingestible device, while in other embodiments one or more coverings cover only a portion of the housing the ingestible device (e.g., parts of the housing with an opening, parts of the housing that comprise enteric materials, or parts of the housing assembled from two or more different modules after the modules are joined together to form an ingestible device). Examples of covering materials include foils, films, and other materials that degrade or erode in the GI tract, and/or that are made of a relatively low mechanical strength material (e.g., so that a dispensable substance can pass through the covering and exit in the form of a jet after triggering). In some embodiments, one or more coverings are made of a gelatin material, for example, using a gel-enrobed technology such as PressFit® or XPressFit® gelcap from Lonza (see, e.g., U.S. Pat. Nos. 5,317,849, 5,460,824, 5,464,631, 5,511,361, 5,795,588, 5,609,010, 6,080,426, and 6,245,350). In some embodiments, the one or more coverings are applied to the device housing using a cold-shrink process. In some embodiments, the one or more coverings degrade or erode in the stomach or in the proximal small intestine (e.g., in the duodenum).

As a further example, while certain embodiments of an ingestible device have been described in relation to certain forms of delivery (trans-epithelial, epithelial, topical), the disclosure is not limited in this sense. As an example, in some embodiments, a device described for use in trans-epithelial delivery or for use in epithelial delivery can be used in topical delivery. Generally, such embodiments involve modifying the relevant parameters (e.g., internal pressure, fluid pressure) accordingly. As another example, in some embodiments, a device described for use in epithelial delivery or for use in epithelial delivery can be used in topical delivery. Generally, such embodiments involve modifying the relevant parameters (e.g., internal pressure, fluid pressure) accordingly.

As another example, in some embodiments, one or more of the components of an ingestible device that contact the dispensable substance (e.g., a reservoir, a housing) include a cyclic olefin copolymer (“COC”). In some embodiments, one or more portions of the housing are formed of a COC, and/or the drive coupling (e.g., piston) is formed of a COC. COCs can be advantageous because they are relatively inert to certain therapeutic agents, such as monoclonal antibodies. Examples of COCs include those which are commercially available, such as those found at http://polymerdatabase.com/Polymer%20Brands/COC.html, which is incorporated by reference herein. Examples of commercially available COCs include Topas (5013/6013/6015/8007), Zeon (Zeonex) and Mitsui (Apel). In some embodiments, one or more of an ingestible device that contact the dispensable substance (e.g., a reservoir, a housing) include one or more cyclic olefin polymers (COPS), silicon dioxide, Resin CZ (Daikyo), polyetheretherketones (PEEKS) (e.g., Solvay (Ketaspire) or Invibio (Peek Optima)), polysulfones (PSs) (e.g., Solvay), one or more ethylene tetrafluoroethylene (ETFEs) Chemours or St. Gobain). In general, such materials are compatible with a wide range of drugs and drug formulations. In some embodiments, a reservoir and/or a housing is made of a different material, and the interior surface of the reservoir (which contacts the dispensable substance) is coated with said material. As an example, a reservoir and/or a housing can be made of polycarbonate coated with one of the noted materials.

As yet a further example, in some embodiments the surface of an ingestible device is very smooth. However, in certain embodiments, the outer surface of an ingestible device has a non-zero degree of roughness. In such embodiments, having a non-zero degree of roughness for the outer surface of an ingestible device may result in a relatively desirable navigation of the ingestible device navigate through the GI tract of a subject. As an example, an ingestible device having an outer surface with a non-zero rugosity may pass through one or more regions of the GI tract in a relatively slow manner. In some embodiments, an ingestible device can have an outer surface with a non-zero rugosity can include, for example, one or more regions that are grooved. An outer surface with a non-zero rugosity can, for example, allow for more time and opportunity to deliver one or more dispensable substances when the ingestible device is disposed within an appropriate region of the GI tract. Such a device can be used for delivery as desired, including, for example, trans-epithelial delivery, epithelial delivery or topical delivery. Generally, the parameters for such delivery are similar to those described elsewhere herein.

As still a further example, while various embodiments of ingestible devices having one or more nozzles have been described in which the exit(s) of the nozzle(s) is flush with an exterior surface of the ingestible devices, the disclosure is not limited to such embodiments. For example, an ingestible device having one or more nozzles may be configured so that the nozzle exit(s) extend outwardly from one or more regions of the outer surface of the ingestible device. In some embodiments in which an ingestible device includes one or more nozzles that extend outwardly from one or more regions of the outer surface of the device, the nozzle(s) are disposed on a longer axis of the device. In another embodiments in which an ingestible device includes one or more nozzles that extend outwardly from one or more regions of the outer surface of the device, the nozzle(s) are disposed on the radial axis of the device. Such an arrangement can allow for enhanced alignment with the surface of the GI tract, e.g., the one or more nozzles are in closer proximity to the mucosal tissue of the GI tract. More generally, any ingestible device described herein having one or more nozzles can be configured such one or more of the nozzles extend outwardly from one or more regions of the outer surface of the ingestible device.

As an additional example, while certain capsule shapes have been disclosed, the disclosure is not limited to such shapes. For example, in some embodiments, the diameter of the capsule adjacent one end that is substantially different (e.g., substantially smaller) from the diameter of the capsule adjacent to the opposite end of the capsule. An example of such a capsule is a droplet-shaped capsule. In certain embodiments, a capsule have a shape described in the present paragraph may allow for the capsule to get relatively close to the mucus (and, as a result, relatively close to the epithelial layer) of the GI tract.

As another example, in some embodiments, an ingestible device is less dense than the fluid present in one or more (e.g., all) regions of the GI tract that are of interest in using the ingestible device to delivery one or more dispensable substances. Such an ingestible device can pass through one or more regions of the GI tract in a relatively predictable fashion, which can enhance the ability to deliver the one or more dispensable substances to one or more desired locations in a relatively controlled and/or predictable fashion. In some situations, an ingestible device is less dense than the fluid present in one or more (e.g., all) regions of the GI tract that are of interest in using the ingestible device to delivery one or more dispensable substances can be referred to as not being buoyant.

As another example, while certain examples of embodiments of a seal (e.g., a foil seal) for a nozzle exit have been described, the disclosure is not limited to such seals. More generally, a seal for a nozzle exit can have any shape and be formed of any material such that it resists breakage until breakage is desired. In addition, a seal for a nozzle exit can be in the interior of the device (e.g., on the surface of the drug reservoir) whereby the entrance to the nozzle is sealed. In some embodiments, a seal for a nozzle exit can be formed of ethyl cellulose (e.g., EthoCel) or polyvinyl acetate (e.g., Kollicoat). In certain embodiments, a seal can in the form of a film, such as, for example, a film having a thickness of from about 10 μm to about 50 μm (e.g., from about 20 μm to about 40 such as about 30 μm). In some embodiments, a seal for a nozzle exit can be formed of a coating that covers some or all of the exterior surface of the capsule material, including the nozzle exit(s) to be sealed. Such coatings can be a monolayer coating or a multilayer coating. Materials that can be used in a monolayer coating include cyclic olefin copolymer (COC), polytetrafluoroethylene (PTFE), thermopolymers, and cellulose acetate. The thickness of such a monolayer can be, for example, from about 25 μm to about 200 μm (e.g., about 35 about 75 about 140 about 200 μm). In some embodiments, the coating is a 140 μm COC monolayer. COC is commercially available from, for example, TekniPlex. In certain embodiments, the coating is a 75 μm PTFE monolayer. In some embodiments, the coating is a 200 μm PTFE monolayer. In certain embodiments, the coating is a 35 μm cellulose acetate monolayer. In some embodiments, the coating is a 75 μm cellulose acetate monolayer. Cellulose acetate is commercially available from, for example, Agar Scientific. A multilayer coating can be formed of, for example, a layer of COC and a polymer layer (e.g., polychlorotrifluoroethylene (PCTFE)) with a tie layer therebetween. Such a multilayer coating can have a thickness of from about 25 μm to about 75 μm (e.g., about 50 μm). For example, a multilayer coating be formed of a layer of COC (e.g., 20 μm), a tie layer (e.g., 16 μm) and a layer of polychlorotrifluoroethylene (e.g., 15 μm). An example of such a commercially available multilayer material is Tekniflex CTA160 (TekniPlex). As noted above, in some embodiments, the seal for a nozzle can be a polyolefin material, for example, having a thickness of from about 40 μm to about 60 μm (e.g., about 50 μm). An example, a commercially available polyolefin Trans-Pharma TRA-150 (Tanscendia). In certain embodiments, a seal can be composed of LDPE, for example, having a thickness of from about 10 μm to about 100 μm (e.g., from about 20 μm to about 80 μm, about 25 μm, about 50 μm, about 100 μm). An example of a commercial supplier of such LDPE is Goodfellows. In some embodiments, the seal for a nozzle can be composed of polyethylene terephthalate (PET), for example having a thickness of from about 5 μm to about 15 μm (e.g., about 13 μm), such as can be acquired from Nordsen Medical. As disclosed above, in certain embodiments, the seal for a nozzle can be composed of PTFE, for example having a thickness of from about 50 μm to about 250 μm (e.g., about 75 μm, about 75 μm), such as can be acquired from RS Components. In certain embodiments, the seal for a nozzle can be composed of fluorinated ethylene propylene (FEP) or nylon (e.g., nylon 12). In some embodiments, the seal for a nozzle can be formed of a metal (e.g., a metal foil). An example of such a metal is aluminum, such as household aluminum foil. In some embodiments, a film containing a metal may have a multilayer construction.

As an additional example, while various examples of general categories and specific examples of materials have been described above, the disclosure is not limited to such materials. In general, according to the disclosure, any appropriate material can be used for any component of an ingestible device. A non-limiting list of general types of materials includes water soluble materials, water insoluble materials, biodegradable materials, non-biodegradable materials and pH dependent soluble materials. In some cases, a given material may fall within more than one such type.

In some embodiments, one or more components of an ingestible device can include one or more thermoplastic materials, e.g., which may facilitate efficient absorption and access to the blood stream in the gastrointestinal tract. Additionally or alternatively, one or more components of an ingestible device can be formed of one or more water soluble polymers, water insoluble polymers, biodegradable polymers and/or a pH-dependent polymers. In some embodiments, suitable polymers may be selected and adapted to have a desired degradation rate and/or dissolution rate. Alternatively, or additionally, a degradation rate and/or dissolution rate may be fine-tuned by associating or mixing other materials as described herein. In some embodiments, a thermoplastic material may for example be polymers that may be formed by heat and may be used to create desired shapes of the material. In one embodiment, thermoplastic materials may be manufactured to the desired shape by injection molding, for example, 3D-printing or hot melt extrusion. In some embodiments, an ingestible device can include one or more components that include one or more starch based polymers, cellulose based polymers, synthetic polymers, and/or biodegradable polymers. In some embodiments, a thermoplastic polymer may be made up of long, unlinked polymer molecules, generally with a high molecular weight. Because the molecular chains may be unlinked, they rely on other interactions, such as dipole-dipole interactions, aromatic ring stacking, or Van der Waals forces. Thermoplastics generally form a crystalline structure when cooled below a certain temperature, resulting in a smooth surface finish and significant structural strength. Above this temperature, thermoplastics may be elastic. As the temperature increases, thermoplastics gradually soften, eventually melting.

In some embodiments, one or more components of an ingestible device can include one or more starch based polymers, such as one or more thermoplastic starch polymers. In some embodiments, the starch based polymer may be starch as such or a polymer having a high starch content selected from more than 70% starch, more than 80% starch, or more than 90% starch. Examples of molecules in starch include amylose and amylopectin. In some embodiments, a starch-based polymer can be general fully biodegradable. In some embodiments, a starch based polymer may be maize starch, such as, for example, Cornpack. A starch based polymers may be decomposable. In some cases, a starch based polymer can be relatively stable and relatively inert in solid dosage forms.

In some embodiments, one or more of the components of an ingestible device can include one or more cellulose based polymers. A cellulose based polymer may be cellulose, wherein one or more of the free —OH groups have been substituted with an R-group to form a —O—R group. R may in this context, for example, be linear or branched lower alkyl, linear or branched lower alkyl-OH, linear or branched lower alkyl-COOH, —CO-(linear or branched lower alkyl), nitrate, aromatic rings or combinations of the aforementioned. Lower alkyl is preferably a C_1-10 alkyl, more preferably C_1-6 alkyl. A cellulose based polymer may, for example, be one or more selected from ethyl cellulose, cellulose acetate, cellulose propionate, cellulose nitrate, methylcellulose, carboxymethylcellulose and salts thereof, cellulose acetate phthalate, include hydroxypropyl methylcellulose phthalate (HPMC-P), ethylhydroxyethylcellulose, ethylmethylcellulose, hydroxyethylcellulose, hydroxyethylmethylcellulose, hydroxypropylcellulose, hydroxypropyl methylcellulose, hydroxymethylcellulose and hydroxymethylpropylcellulose and cellulose acetate.
